Changes

• Support loading config files relative to cwd in 40d885b

  This will recursively search up from the cwd for a pruner.toml file
  and merge this with the global .config/pruner/config.toml file.

  If --config is specified then this is used instead.

• Add support for wasm formatter components in bb33627

  This change bakes in an embedded wasmtime engine which can load and run
  wasm components implementing the formatter wit interface.

  This allows extending pruner with 'native' formatters which can be
  written in any language that can compile to wasm, and can operate on any
  language source code.

  As an example, an initial trim_newlines wasm formatter is included in
  this repo.

• Fix indent bug in non-formatted injected region in b46a009
• Improve initial README description in c6d4864
