MAINT: Check for buffer interface support rather than try/except
This checks for buffer interface support using `PyObject_CheckBuffer`
up-front. That seems to shave off about 100ns e.g. when importing
pandas DataFrames (which do not support the buffer interface, but
do support `__array__`.
The reason is that building a TypeError and then clearing it takes
time.
It felt like a clear, easy win, since the check should be so fast
that checking twice (in the case that it is indeed a buffer) does
not really matter.
But, if nobody likes to think about it just close :).
