Fixed dtype validation in _USMBufferData auxiliary class

np.number comprises np.integer and np.inexact, so replace
issubdtype(dt.type, np.inexact) or issubdtype(dt.type, np.number)
with more efficient issubdtype(dt.type, np.number).

Also allowed dtype.type to be np.bool_, to accommodate dtype="|b1"

Replaced single quotation marks with double quotation marks per
linter's flavor.
