dgCMatrix parsed without dim names

[nuno-agostinho]

Hi all,

When parsing dgCMatrix objects (and maybe other sparse matrix classes), the Dimnames attribute is missing in the parsed object.

The issue seems to come from the following lines:

rds2py/src/rds2py/read_matrix.py

Lines 95 to 99 in c78706a

	names = None
	if "dimnames" in robject["attributes"]:
	names = _dispatcher(robject["attributes"]["dimnames"], **kwargs)
	if names is not None and len(names) > 0:
	return MatrixWrapper(mat, names)

As per the CsparseMatrix documentation (superclass of dgCMatrix), the attribute should be called Dimnames (not dimnames).

It would be fantastic if this could be addressed. Thank you for this amazing project! :)

All the best,
Nuno
