Version 5.3.0

The main new feature (and motivation for a new minor release, 5.3.0), is that Uproot now strictly depends on the cramjam library for compression, rather than optionally depending on lz4, xxhash, and zstd (prompting users to install them when needed, rather than upfront when Uproot is installed).

New features

• feat: use cramjam for lzma, lz4, and zstd, opt-in use of isal for zlib by @lgray in #1090
• feat: expose decompression_executor and interpretation_executor in uproot dask by @ioanaif in #1120

Bug-fixes and performance

Full Changelog: v5.1.2...v5.2.0

Version 5.2.0rc5

The only change in this release is that it's made from the main branch, with main-fsspec (all of the 5.2.0 changes) rebase-and-merged into it. Thus, the order of the applied diffs may be a little different, but it should be the same code. If this pre-release is acceptable, we will follow with 5.2.0 with no changes. (5.2.0 will have a longer set of release notes because it will show differences with respect to 5.1.2.)
