Adding light curve feature for the source injector

[GallegoSav]

This is an important feature transient people would like to get I suppose. No need to simulate all the transients sources.

I was thinking about taking this into account in the livetime of the Spacecraft class. Can we assume for example if at the time t the flux is multiply by 2, this is equivalent to multiply the livetime by 2 ?

The user could provide a light curve file and the livetime column would be updated accordingly.

What do you think @israelmcmc , @ckarwin and @hiyoneda ?

Yes, I agree this is important. Thanks, Savitri.

The livetime indeed needs to be multiplied by flux vs time during this calculation, but it doesn't need to be modified within the SCHistory class, just during the calculation. In fact, it's better if the SCHistory remains constant after the initial setup by the user (e.g. applying GTI, downtime, etc.)

There are also 2 types of output needed: time-binned and time-integrated and
