bladder pdo transcriptomics table not formatted correctly

[ymahlich]

Importing the newly generated bladderpdo dataset from figshare (generated and deposited via #359) the resulting Dataset.transcriptomics does not have the correct column names.

Expected behavior:

>>> bladderpdo = coderdata.load(name='bladderpdo')
>>> bladderpdo.transcriptomics.columns
Index(['entrez_id', 'improve_sample_id', 'transcriptomics', 'source', 'study'], dtype='object')

Observed behavior

>>> bladderpdo = coderdata.load(name='bladderpdo')
>>> bladderpdo.transcriptomics.columns
Index(['entrez_id', 'value', 'improve_sample_id', 'source', 'study'], dtype='object')

As you can see the column transcriptomics currently is called value.
This should be an easy fix, but currently breaks all existing downstream processing for the bladderpdo dataset

In the bladderpdo transcriptomics file, there are also missing improve_sample_ids and entrez_ids
