Arbitrum Nitro v2.0.1

What's Changed

This release contains a fix to gas estimation for some transactions with very compressible data, along with the start of config hot reloading which is currently only supported for changing the log level.

• Add config hot reloading (for limited fields for now): #973
• Assume current validator stake is valid in the block validator: #1032
• Separate stateless block validation (allows you to validate a particular block without being a full validator): #1034
• Lots of documentation updates in various PRs!

Internal Highlights

• Add configurable interval to create assertions at: #1027
• Add a gas margin to the batch poster: #951
• Add clarity to sequencer batch error logging: #1038
