Size (binsize)

Shell and python scripts acting as wrappers around binsize tool/command.

Adding --help to any <command>.sh will show the help message for that specific command.

Settings of this specific (trezor-firmware) project are forwarded in each command. Specifically, core/build/firmware/firmware.elf and core/build/firmware/firmware.map (optional) files are used and we are interested in .flash and .flash2 sections.

bloaty and nm tools are needed.
