Closes #93

- Removes repeated code in generating PSDs from frame files.
- Fixes a few minor bugs elsewhere

Note - this is the default for get_interferometer_with_fake_noise.., not
the default in general.

Makes the options to set the PSD methods. Retains the default behaviour
(will use aLIGO if nothing is set). But now, users must call a
`set_from_` method after initialising the PowerSpectalDensity()`.

Also adds logging messages

Previously, set_from_frame not only loaded in the time domain data, but
also applied a filter and FFT'd. This is no longer required and has
hence been removed.

- Fix error in create psd
- Fix minimum and maximum frequencies
- Improve documentation

Adds functions to set the strain data from open data, generate a PSD,
filter, and window.
