[Cin] New SVT-AV1 release: v2.3.0 from AOM

[Phyllis Smith]

Built successfully the 2.3.0 version and checked into GIT and Andrey's
package are in the process of building now. Ran 2 tests and all seems
normal - it may be slightly faster and the file generated may be slightly
smaller but it is too hard to tell with my simple tests. Thank you Terje
for the notify of the new version.
