remove column assignment to improve compatibility with new cell metad…

[cornhundred]

Description

This pull request addresses this issue #647 where the read function is unable to support updated versions of cell metadata (see https://vizgen.github.io/vizgen-postprocessing/output_data_formats/entity_metadata_format.html). We remove the assignment of column names to allow for modifications to cell metadata.

How has this been tested?

I have tested that this modification allows squidpy to load the previous and current versions of cell metadata.

adata = sq.read.vizgen(
...   'Mouse_Brain_Showcase/', 
...   counts_file = 'cell_by_gene.csv', 
...   meta_file = 'cell_metadata.csv')
