Update item stack, compound tag, fluid stack and fraction serialization

[kirderf1]

• Item stack data tags are serialized differently now, using a new compound tag adapter (with backwards-compatibility for the previous format)
• The item stack adapter has been touched up a bit
• Fraction is now serialized using a codec (it was previously serialized through nbt that was converted between json)

Fixes #654 and #649 (and related to #643) in 1.18. If the PR gets accepted, I assume that I'm fine to backport it to 1.16 without going through a PR. As this change changes the save format, it might make sense to let the next HQM version be 5.11.0. However this change is really only for code cleanup and fixing some issues, so it might not quite meet this standard. Should the next version be 5.10.1 then, rather than 5.11.0? When this gets backported to mc 1.16, it'd be HQM 5.5.17 as HQM 5.6.x is in mc 1.17.

PR looks good. I can't validate if it works, but I assume you did. For the version, just use the lowest value, so 5.10.1 and yeah you can push the backportd directly
