Subject: [PATCH] Allow for disabling auto-formatting

Allow for disabling auto-formatting with a global or buffer-local
variable, based on
https://github.com/stevearc/conform.nvim/blob/62eba813b7501b39612146cbf29cd07f1d4ac29c/doc/recipes.md#autoformat-with-extra-features.

In the future, it would be interesting to do this based on the presence
of a file in the repository, such as `.do-not-auto-format`.
