Correct pyproject.toml build-backend specification

[nchepanov]

Currently:

yaspin/pyproject.toml

Lines 75 to 77 in 2c78d24

	[build-system]
	requires = ["poetry>=0.12"]
	build-backend = "poetry.masonry.api"

According to https://python-poetry.org/docs/pyproject/#poetry-and-pep-517

If your pyproject.toml file still references poetry directly as a build backend, you should update it to reference poetry_core instead.

Should be updated to,

[build-system]
requires = ["poetry_core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

This will significantly speed up the package installation process, since the entire poetry dependency cone is currently being installed during isolated build per PEP517.

I can submit a PR if no objections.

Hi @nikitos3000

Thanks for pointing this out! I'll happily accept the PR.

Hi @pavdmyt thank you for approving the PR. How do you feel about releasing a 1.3.1 version?

[pavdmyt]

I'll include this PR as well as a bunch of others in v1.4.0. If everything goes well, I'll do it this weekend.
