Rebase to upstream release, 1.21.0.0.0.
Resolves: rhbz#1972029

Store the upstream version (currently "1.0-SNAPSHOT") and snapshot info completely in the Version field rather than using Release.
Resolves: rhbz#1972029

Update to latest upstream version with renamed package and consistent use of "jigawatts"
Drop library patch which is no longer needed.
Resolves: rhbz#1972029

Rewrite to use autotools build system, avoiding need for Maven dependencies missing in RHEL 9.
This also ensures use of the standard build flags and installs the jar in the expected location.
