[flashprog] flashprog v1.3-rc1 ready for testing

Hi all, in preparation for the v1.3 release, the first RC has been tagged. It's available through the Git tag `v1.3-rc1' and as tarball [1]. Please test! :) Most notable changes are support for newest Intel chipsets and a new CLI infrastructure. Which brings two special com- mand modes to configure SPI flash chips. Please see $ flashprog wp --help and $ flashprog config --help and the new man pages flashprog-write-protect(8) and flashprog-config(8). Feedback on these is particularly welcome. Cheers, Nico [1] https://flashprog.org/releases/flashprog-v1.3-rc1.tar.bz2
