Closes #29

Here are some questions I have punted on so far:

• [ ] What is the (formal) uncertainty in the mass loss rate? What is the systematic uncertainty?

Really this needs an MCMC to do correctly... but while varying the uncertain XUV.

• [ ] Is it possible to frame [number of visits] in terms of the actual phase coverage surrounding transit? Like a well-sampled range spanning -0.22 to +0.18 of the orbital period about the transit event (or something like this with real numbers)?

Yes, we should say this

• [ ] Can the position of the stellar companion (HAT-P-67 B) be used to clarify the age?

My gut instinct is no? There's not enough evolution in a M-dwarf between those two time points.
