feat: add daemon service to MutagenSdk (#56)

- Adds support for an array of protobuf "entry points" in
`Mutagen/Update-Proto.ps1`
- Also refactors file modification/writing to be more efficient and to
not include an unnecessary byte order mark and two trailing new lines
- Adds Daemon service to `MutagenClient`
