02fa34089623ea43e9c62003e3b829d10dec5a14 chore: remove bdk dependency on log and dev dependency on env_logger (Steve Myers)

Pull request description:

  ### Description

  As suggested by @TheBlueMatt we shouldn't use the `log` crate because even though it is a rust-lang project is may depend on some other crates that aren't as well maintained. Since we were only use `log` in a few places and not it any other bdk workspace projects except the `bdk` package I removed it.

  ### Notes to the reviewers

  For consistency I also removed the `env_logger` from the dev dependencies since it was only being used in a few places in a couple examples and println! is adequate for examples.

  ### Changelog notice

  None
