9fc5bb546b style(core): full pyright-based type-checking 
Changes many fields to required -- as far as we were able to figure out,
signing would fail if these fields aren't provided anyway, so this
should not pose a compatibility problem.

391976bcda refactor(core/usb): do not require serial number on instantiaton of USB 
On a cleanly wiped device, storage must be unlocked in order to create
and retrieve the serial number. However, storage unlocking happens in
boot.py, which is imported _after_ usb.py

We must therefore sidestep asking for the serial number.

872e0fb0e0 core: lower scheduler resolution to milliseconds 
This avoids problems with large timeouts causing the scheduler queue to
think the time counter has overflown, and ordering the autolock task before
immediate tasks.

The maximum reasonable time difference is 0x20000000, which in
microseconds is ~8 minutes, but in milliseconds a more reasonable ~6
days.

2658e253fa xmr/bp: memory optimizations and improvements 
- different approach to vector manipulation - more on the fly operations. Prepared for fully offloaded operations, BP on Trezor with constant memory.
- memory requirements reduced from (4MN + const) to (2MN + const)
- more raw methods to avoid unnecessary encoding/decoding
- chunking improved, chunk size set as a constant, changed from 64 to 32, missing pieces implemented to cover also BP 16
- proof_v8 support discontinued, old hardfork, not needed anymore
- get_exponent register clash fixed (for large vectors)
- reduced heap fragmentation by removing some temporary allocations
- hashing with len and offset to reduce heap fragmentation by creating a sliced arrays
- use to() wherever possible to avoid allocations and return of mutable private object
- global functions start with _ prefix, reduce import footprint
- use __slots__ in classes to minimize footprint

c81be584fb core/fatfs: ensure functions can only be called on a mounted filesystem 
ff.c has a lazy-mounting feature, where any filesystem call will mount
the volume if it can. This messes with predictability of the mounted
state, so all (except mount/unmount/mkfs) Python functions will first
check if the fs is mounted.

fa746e2990 core/fatfs: rework low-level FatFS API 
Instead of having possibly multiple FatFS objects, each with its own
`fs` struct, there is one global static fs_instance. This is to match
the mode of operation of ff.c, which assumes a global list of mounts,
and all functions operate on the global based on path.

Methods of FatFS were converted to functions on the fatfs module.

fatfs.unmount() does not call ff.c's unmount, but simply invalidates
fs_instance. This is basically what ff.c would do, except without
messing with ff.c's global list of mounts.
