Config file and "profiles"

[alcarney]

It would be useful for lsp-devtools to be able to read configuration from say pyproject.toml.

This would open the possibility of introducing named profiles as shortcuts to common use-cases e.g.

• lsp-devtools record --profile log => lsp-devtools record -f "{.params.type|MessageType}: {.params.message}"
• lsp-devtools record --profile registration => lsp-devtools record --include-method initialize --include-method client/registerCapability --include-method client/unregisterCapability
