tracking: Performance

Binary size

As of now (11/9), the generated UF2 file with full functionality enabled in the min-size profile is about 250kb. I want to maintain this binary size as much as possible.

Performance

There don't appear to be any significant performance issues at present.

Memory size

This needs to be improved. A panic occurred with 128kb of memory.
I think rktk-keymanager is using too much memory.

The increase in stack size was caused by the nature of the arguments being stored in future. By using pass-by-reference as much as possible, the stack size was greatly improved. (commit dcf2c8a)
rust-lang/rust#62958 This issue may be related, but I'm not sure if this problem can be solved by optimization.
