This release mostly contains refactoring and dependency updates, and some improvements in log operation cycle.

Improved log operation

Merkle refactoring

• Packages under merkle are deprecated and to be removed in the next releases [#2636, #2646, #2715].
• Use https://github.com/transparency-dev/merkle repository instead.

Minor refactoring

• Check the tile height invariant stricter [#2726]
• Remake dumplib into integration test [#2710]

• Unexport helper [#2720]
