feat: add v0 go batch submitter and gh actions integration

For some reason the log level environment variables aren't being picked
up, and neither is the default value for the flag being applied to the
final binary when run in docker. Remove this commit once a fix is
established.

Attempting to compile L1 and L2 get in the same binary produces a
symbole collision since the CGO names for the library methods are
identical. To avoid this, we simply reexport the L1 secp256k1 members
that rely on CGO.

feat: tweaks from final SDK behavior review
