Crate re_log

Text logging (nothing to do with rerun logging) for use in rerun libraries.

Provides helpers for adding multiple loggers, and for setting up logging on native and on web.

• trace: spammy things
• debug: things that might be useful when debugging
• info: things that we want to show to users
• warn: problems that we can recover from
• error: problems that lead to loss of functionality or data

The warn_once etc macros are for when you want to suppress repeated logging of the exact same message.
