VStar and Gaia DR3 epoch photometry

Gaia Data Release 3 brings us an extensive light curves database (epoch photometry). The data are sparsed yet could be helpful in combination with other surveys to refine variable star parameters. Currently, VStar cannot open the Gaia DR3 epoch photometry directly.

I wrote a 'recipe' ( https://github.com/AAVSO/VStar/wiki/Working-with-Observation-Sources#accessing-gaia-dr3-epoch-photometry ) on how to convert Gaia DR3 photometry data accessible through https://gaia.aip.de into 'Flexible Text Format' which VStar can work with. It requires Python to be installed.
