watcher: add recipe

[toge]

Specify library name and version: watcher/*

---

• I've read the guidelines for contributing.
• I've followed the PEP8 style guides for Python code in the recipes.
• I've used the latest Conan client version.
• I've tried at least one configuration locally with the conan-center hook activated.

You use subprocess.run and pass a timeout: https://docs.python.org/3/library/subprocess.html#subprocess.run

[toge]

@uilianries Thanks! I will try.

@uilianries
I have finished.
But watcher released newer version and updated example which uses thread.

I will rewrite test_package.cpp to follow upstream example.

Is this is from a commit or PR please add a link but this does not seems like a "backport" ad defined by the docs

Suggested change

	patch_type: "backport"
	patch_type: "portability"

[toge]

@prince-chrismc
I agree with you.
I am going to create PR for upstream.

[toge]

Fixed.

[prince-chrismc]

Super minor nits otherwise this is perfect
