now that we create segmented UF2 files properly in concatenate, we need
the ability to read them, which we'd previously saved for later; that
time is now. the reader now supports jumps forward (but not backwards,
and I don't know how likely it is we'll ever see this)

this is in preparation for making smaller .uf2 files buy not needing
padding, instead passing multiple location+binary combos to the
converter

the prior version, for the board/user configs, took the whole ~2MB
binary file and converted it to a UF2, which made for a lot of chunks
that were just writing 0s, between the end of the firmware and the start
of the config(s). this changes the logic to build each portion as
separate UF2 chunks and then combine them.

the former is to avoid an upcoming circular dependency, the latter is to
allow for creating an e.g. user-config-only .uf2 by specifying the
proper offset to start the UF2 addressing at.

prior MIT-licensed versions can be obtained from the Git history; this
does not revoke those versions

current libraries seem to have problems on Windows with thinking files
are duplicated when they are not, making it impossible to compile .proto
files at runtime in this tool on that platform. this adds a fallback of
using shipped, precompiled files in the package. I was already intending
on providing this as an option anyway, so might as well start doing it
now.

this also bumps the proto files in the test directory as a matter of
convenience, so some tests got updated accordingly

prior to this, the concatenate assumed it was concatenating a firmware
with a full *storage section*, e.g. the already-padded 8192 bytes, but
it's equally valuable now that I'm creating configs to have just a
config section + footer, which needs to be padded 8192. now concatenate
supports both
now you don't need to fiddle with specific byte ranges of a dump, you
can just dump the whole board if that's more convenient, and
visualize-storage will parse that
also more testing in general
