Currently when the the bootloader is modified if fails to build because
the wildcard in the hex merge picks up both the old and new binaries.
Fix this by explicitly deleting the old one.

Currently there's no fancy algorithms to estimate stride length. Just
pure simple step counting directly from the hardware's "intelligence
engine".

The micropython build system has incomplete dependancy tracking, especially
with regard to frozen manifests. Work round this by nuking the frozen
content before attempting a build. Sure this is a hack... but much
better than developing a "make clean; make all" habit.
This not only avoids the use of a deprecated feature but it also
makes it easier to decouple the wasp/ directory structure from
what actually gets copied to the target.
