Add scripts to aid in constructing github releases of the maiko artifacts (#395)

Until these are superceded by github actions, if the github CLI tool "gh"
is installed, a github release of the maiko code can be created by running
   ./start-release
from the maiko/bin directory, and then running
   ./release-one
for each combination of OS/architecture that should be included in the
release.

The scripts assume that the maiko code is checked out in a directory
named "maiko" (and may produce unexpected results if run from somewhere else)
