test: cover Go serialization snapshots

[tisonkun]

Summary

• update the pinned datasketches-tck revision and prepare C++, Go, and Java snapshots by default
• add Go compatibility coverage for Bloom, CPC, Frequencies, HLL, TDigest, Theta, and Tuple
• document Go snapshot preparation and ignore generated files

Count-min remains C++-only because the TCK currently has no Go Count-min snapshots.

Testing

• cargo x prepare-testdata
• cargo x check
• cargo x test
• cargo x lint

Closes #170

Thank you!

I will add go count min sketch snapshots generation too.

@proost Thanks for your review and information! Please let me know when it is ready so that I can test Rust's countmin deserialization works well on Go snapshots :D
