Python-lsp-pyre

Updates the default pyre configuration to be strict, and updates the documentation to match. Introduces an internal settings object, because I'm not a fan of dicts and the typing thereof (yes, TypedDict exists).

* Introduces the Settings dataclass
* Uses it to convert the pylsp settings dict to a typed object
* Defaults pyre to strict mode when writing out the initial config file
* Updates the documentation to reflect this strict mode
* Updates the documentation to explain squelching of Pyre lints
* Adds source commentary about pyre's output vs LSP w.r.t. lints per file

This is v0.1.2 of the plugin. It addresses some deficiencies in the documentation, and deals with configuration pass-through from the language server more correctly.

* Adds docs/Configuration.md to detail what configuration options are supported
* Updates docs/kate.md to detail how to pass settings from Kate's LSP config structure
* Updates README.md with more precise details about the configuration
* Updates README.md with more links, reflowed text, reorganised text
* Updates the plugin to default the configuration as "enabled, but don't create pyre config"
* Updates the plugin to log when the pyre config option is somehow missing
* Moves the pyre config file creation out of the `initialize` hook and into the point before running Pyre
* Decorates error messages with the plugin name
