Use the TIC As Input Catalog Rather than UCAC4

[xcthulhu]

Now that the TIC has had a preliminary release, it is time to migrate TESS off of UCAC4

[rkvanderspek]

Different applications may want different TICs, so we should discuss what level of flexibility is needed.

We could have a command line parameter to set it

There are three command line parameters in use already:

• SPYFFIDATA (sets the data directory)
• LOG (sets the log level)
• LOG_FILE (sets where the log file is dumped)

They are implemented here https://github.com/TESScience/SPyFFI/blob/master/settings.py#L14

Alternatively, you could hand the TIC as a field in the input dictionary handed to Observation

This is implemented here https://github.com/TESScience/SPyFFI/blob/master/Observation.py#L24

After that, you would have to hand the argument down to every other method and subobject that Observation produces or calls that might depend on it
