[flashprog] Maintenance release v1.0.2-rc1

Hi, we found two regressions related to the Dediprog driver and large flash chips. There'll be a small maintenance release to fix them. The code of the release candidate is available through the tag `v1.0.2-rc1` and as a tarball[1]. Cheers, Nico [1] https://flashprog.org/releases/flashprog-v1.0.2-rc1.tar.bz2
