Add convenience method to get total phase advances from TEAPOT_MATRIX_Lattice + reformatting

[austin-hoover]

Added method TEAPOT_MATRIX_Lattice.getTunes() which returns the tunes $\nu_x, \nu_y$. It just calls the method trackTwissDataX, which integrates through the lattice to get the phase advance as a function of position, and takes the phase advance at the last integration step.

Note that getRingParametersDict() returns the fractional phase advance from the one-turn matrix, not the total phase advance.

I also added type hints to this file.

Verified that the reformatting does not affect calculations. Before:
