Change Args to a more readable format

[PotatoPalooza]

A large portion of the TensoRF codebase passes around an args object of all command-line arguments that is propagated down to many subroutines. This should be replaced with a more self-explanatory object perhaps a python class that describes the properties in more detail. Along with this, the args object should only be used in the highest level functions instead of passing it through multiple classes and methods making the code harder to understand and modify.
