Duplicacy Command Line Version 3.1.0

• Updated github.com/minio/highwayhash to 1.02 to fix incorrect hashes for Erasure Coding on arm64 [1]: 6a7a2c8

  bc2d762
• Fixed a chunk leak with check -files: b8c7594
• Fixed 2 bugs that are results of handling zero-byte files incorrectly: 3472206

Notes:
[1] The highwayhash is only used to calculate the checksum of each shard in Erasure Coding and not used anywhere else. So you are affected by this bug only if you enable Erasure Coding on arm64 machines. This bug is present in both 3.0.1 and 2.7.2 versions of the macOS m1 builds, and only in 3.0.1 of the linux arm64 builds.

In this release both the correct and incorrect versions of the highwayhash will be calculated so there is no need to fix existing storages, but you can use the newly added -rewrite option to rewrite affected chunks using the correct version of the hash if desired.

[2] If you are using 3.0.1 to copy snapshots created with 2.7.2 or earlier, this bug will affect you. In 3.0.1, the version bit (0 for V2 snapshots and 1 for V3 snapshots) was the only flag used to determine the format of a snapshot. However, in this release, the first byte of the snapshot file is also used to distinguish between V2 and V3 formats. As a result, there is no need to rewrite V2 snapshots that were already copied with the incorrect version bit.
