Telplin

Telplin helps F# users to generate matching signature files for implementation files.
Usage
dotnet tool install -g telplin
telplin src/App/App.fsproj --files App/Api.fs
This writes Api.fsi next to Api.fs, lists it in the project, and keeps only what other files of the project use: a let binding nothing else calls is left out, which makes it private. The project is type checked before and after, so a signature that does not match is never written.
The same, from the file itself: Telplin finds the project it belongs to.
telplin src/App/Api.fs
Pass --keep-unused to get everything the file exposes, and leave out --files to do the whole project. Run telplin --help for the other flags.

### Changed
- An exception while converting one declaration no longer stops the whole run: the declaration is left out and the rest of the file is still produced. The CLI reports every declaration it left out as `file(line,col): error: message`, followed by the source around it with the declaration underlined. Progress lines and warnings go to stderr, so stdout holds only results. [#72](https://github.com/nojaf/telplin/issues/72)
### Fixed
- A member with a `[<DefaultParameterValue>]` whose value is the default of a struct, such as `Nullable<TimeSpan>()`, no longer fails to parse. [#348](https://github.com/nojaf/telplin/issues/348)
- A type declared in a module with `ModuleSuffix` (explicit, or implicit when a type shares the module's name) is no longer qualified with the module name inside that module. [#71](https://github.com/nojaf/telplin/issues/71)
- A backtick inside a backticked name, such as ```` ```a` b`` ````, is escaped correctly. Fixed by the FCS update, now covered by a test. [#88](https://github.com/nojaf/telplin/issues/88)
