Feature request: Documentation on how to write performant Grammar

[cedmoh]

Hello and good day,

I would like to request a documentation page explaining how to write performant grammar. A list of best practices, and what to avoid, as well as some insights as to how rust code is generated from the .pest file by the macro would be super helpful.

This would help users with huge grammar files facing parser timeouts (like myself) to troubleshoot their .pest file.

Thanks in advance!
