s/d/_core.pyx: pedantic typo caught by linting.

Debian's linting tool "lintian" reports the below informational
message in dnaio 1.2.2 (and possibly other versions):

	I: python3-dnaio: spelling-error-in-binary "allows to" "allows one to" [usr/lib/python3/dist-packages/dnaio/_core.cpython-312-x86_64-linux-gnu.so]

This patch applies almost blindly the recommendation, although perhaps
there exists better wording to apply to the desctiption of the symbol.
For what it's worth, I did attempt to find better wording, but lacking
proper context for the function, the recommended change might do.
