RegFile

[perlindgren]

Problem

Visualizing internal state of the register file.

Solution

Preview only recently accessed registers on the component.

• Show all 32 registers in a foldable left panel. (Merged.)

• Allow for formatting options on each register.

Currently the reg_file is in the mips crate, but similar register files will come up for all CPUs. Later we might want to make it more generic and configurable for better re-use.
