[x] Change from current txt metadata file to pkl
[ ] Download LVCNR file if available, else download MAYA format file and convert to LVCNR using mayawaves

@prayush a couple of choices we need to decide on, please let me know what you think:

Converting the psi_4 from maya format files to strain in LVCNR by default extrapolates the waveforms to infinity, but there is also freedom in choosing a finite extraction radius. See this link for details.
Similarly, we have to choose whether to correct for CoM drifts, I am guessing by default we should always correct for CoM drifts?

By default, we need to extrapolate to null infinity and correct for COM drifts. The details of each of these operations are something we should discuss, though.

Things minimally work now, but I think there is still some development that needs to be done to ensure that MAYA data is only downloaded when LVCNR data does not exist. I think this might require changes to the .get method.
