chore: PHPStan ignore line

[tienvx]

Ignore this error:

Cannot access offset 0|1|2|3 on FFI\CData.

For #564

Approving, but just wanting to check: Is it possible to ignore a specific error?

By analogy, in Python we have:

x: int = "foo" # noqa   <-- Generic 'ignore all errors'; bad practice
x: int = "foo" # noqa: some-error <-- Only ignores 'some-error'; best practice

Is it possible to ignore a specific error?

Yes, it's possible, but only when PHPStan version 1.11 is released (sometime in May). The current version is 1.10.67, which is the last version of 1.10, doesn't support it.

So I use 2 solutions, and will remove the other when 1.11 is released.
