Update FC parameter optimization

See merge request !104

- Updated the filter cavity optimization to work with the recent precomp changes
- Removed a redundant argument in computeFCParams

default frequency array for load_budget()

See merge request !106

This specifies a default frequency array for load_budget and the CLI, and makes it easier to provide alternative arrays with a frequency "specification string" (e.g. '5:1000:3000').

noises.py: clean up helper functions

See merge request !107

- merge coating_thickness into mirror_struct
- merge precomp_mirror into mirror_struct
- merge precomp_power into ifo_power
- merge precomp_cavity into arm_cavity

precomp is no longer used for these helpers, but they're sufficiently
trivial that it doesn't matter whether they are cached.

closes #56

fixes bug where overall budget name was used instead.

This fixes a bug whereby references traces were being included in the sum
total.

This prevents buggy behavior if an ifo is not provided.

This function is useful, so no reason to hide it.

closes #72

Fixed the old calculation and added a new term to the quantum sub-budget

cache precomp data between runs

See merge request !103

those variables will be considered internal.

This prevents the precomp data from being re-calculated if the ifo
hasn't changed.

introduce Mirror struct for mirror thermal calculations

See merge request !102

precomp decorator support

See merge request !95

This struct is created by the precomp_mirror function, and is essentially
the union of the Material and Optic structs, holding all relevant
properties for a given optic for thermal noise calculations.  It can be
used in place of either the Material or Optic structs.

Coating thermal noise functions are modified to accept this struct.

This is some cleanup and simplification of Lee's mapped precomp
series.

cache the load status

Add a Struct.hash() method to return a unique hash over attributes.

Modify Noise.run() method to check for changes to the ifo and only run
the update method if the ifo has changed or other kwargs are supplied.

nb.precomp decorator can be used to wrap BudgetItem.calc methods with
functions that only need to be called once per budget run.

    nb.precomp(precomp_foo)
    def calc(self):
        ...

Precomp functions are all executed by the update() method (after attribute
update), and execution state is cached at the Budget level, to prevent
re-calculating the same functions multiple times per update.

The BudgetItem.update() method is no longer expected to be overloaded by
the user.

This provides a speed-up of about 50% for the Aplus model, but much less
for the CE models which are limited by other noise calculations.

API change: Budget/Noise calculations return BudgetTrace object

Closes #59

See merge request !98

This new object holds the PSD and frequency arrays, as well as the
list of all budget sub-noises, accessible via a dictionary interface
and attribute access.

All interfaces and tests are updated to process the new BudgetTrace
object.

A new HDF5 schemata (version 2) is also introduced that stores trace
data in a way that mirrors the BudgetTrace.  The io functions
(save_hdf5/load_hdf5) are updated to write/read this format.  The
load_hdf5 functions continues to support the version 1 SCHEMA.

Closes #59

remove reference to unused BeamRadius parameter in ifo.yamls

Closes #3

See merge request !101

We don't want to advertise these parameters yet, since they will
likely be changed to support different loss functions.
