After the package_rbf fuzz target was updated, the old fuzz inputs produced sub-optimal coverage, so I put together some new fuzz inputs for the updated target.
The old fuzz inputs after https://github.com/bitcoin/bitcoin/pull/30300 was merged:
0[#1188](/bitcoin-core-qa-assets/1188/) DONE cov: 3651 ft: 20819 corp: 388/13927Kb lim: 1041407 exec/s: 132 rss: 618Mb
After fuzzing a bit and creating a fresh set_cover_merge from old and new:
0[#195](/bitcoin-core-qa-assets/195/) DONE cov: 3676 ft: 21559 corp: 193/15247Kb lim: 796083 exec/s: 24 rss: 580Mb
I decided to merge the result from the set_cover_merge rather than replacing the old fuzz inputs, so that the fuzz test continues to work for older versions of the master branch and the latest major release.
