Issue in setRTL where if a componant
was previously specified as `m`
and L and T are set, R
would not be overriden and
so would result in an error

beamTrace and plot_beam_trace are two
beam tracing algorithms which use different
methods to compute the beam trace.

Here I update the docs so these point to one
another

pykat.kat.beamTrace was defaulting to 1.064um
wavelenght when producing a beam trace.

This was likley a bug. I have updated the
code so the wavelength is preserved. Some results
for a simple telescope match my analytics
and also match a Finesse simulation with a
`bp` detector placed at several nodes.

Tested at 2um wavelenght.

Catch stderr from 'kat -v ' and 'kat -h' commands to ensure we catch dynamic library errors

There was a bug introduced in 3753e703
were setting fx and fy using the pykat interface
resulted in an error. This has been fixed and
unit testing added

pykat.optics.maps.surfacemap.writeMapPrepResults
has a bug where a new line character was missing
from the map info results.

This made the finesse_info files difficult to parse

I have added the new line character

Testing: I have tested the new function
with some mirror maps.

fixed issue in readOutfile when the outfile is moved by the save_output options

Parsecommands was deprecated, it had been updated.
pylab was also depracated I have changed to pyplot
I have also added some extra kwargs to enable returning the data
and diabling specific plots, which I find useful.

The default behaviour is unchanged.

The expanded interface allows plotting the foward and return
beam profiles which is useful for mode matching problems, e.g.
```python
fig,ax = plt.subplots(nrows=2,sharex=True)
plot_beam_trace(setup.deepcopy(),"nITMY1a","nSRM1",size_axes=ax[0],gouy_axes=False,fig=fig)
plot_beam_trace(setup.deepcopy(),"nSRM1","nITMY1a",size_axes=ax[1],gouy_axes=False,fig=fig)
```

Virgo file wasn't running from, frequency constants f4b and such were commented out but still used in detectors? Renabled them. Adding strain plotting for adv, has DARM_h DOF now

fixed a bug in which the pwd and IFO arguments were swapped when given to _run in parakat

See merge request finesse/pykat!9

The background for the area outside the axes window was previously transparrent. This makes it white.

Resolve "Pykat should not catch parse errors and exit"

Closes #14

Transfer function bugix and minor AdV class updates

See merge request finesse/pykat!7

fixed typo in the tf class that caused all the zeroes to be converted to poles by the getFinesseText method
