Add new domain, remove unused function, and fix rop function dispatch

[hwpang]

• I added a new domain ConstantTLiqFilmDomain whose volume expands as the film grows. Its volume changes based on the mass of the film domain, where dV/dt = dm/dt / rho / (1 - epsilon) * epsilon, where rho is the density of the solid, and epsilon is the porosity of the film (vol frac of liquid in film)
• I removed an unused function as film growth reactions are treated as interface now
• I added "mass" as a column in the rop matrix and changes to address the issue Fragment array functions in Simulation.jl are overwriting other helper functions #219.

The simulation test is failing, but I've given comments on the changes.

[hwpang]

Change log:

• Rebased with main
• Split the function to two separate functions, one returns ropmat as normally would, and the other returns ropmat and massropvec.

Look good. One quick question.
