Update aggregation to match ancestry output

[nebfield]

Doing this in the quarto report with data.table causing problems with building the dockerfile.

Also, this fixes an issue where the DENOM column is missing when multiple custom scoring files are aggregated

Will need to change read_pgs in ancestry_analysis, as it reads in the old version of the aggregated scores.

pgscatalog_utils/pgscatalog_utils/ancestry/read.py

Lines 74 to 87 in c672be7

	def read_pgs(loc_aggscore, onlySUM: bool):
	"""
	Function to read the output of aggreagte_scores
	:param loc_aggscore: path to aggregated scores output
	:param onlySUM: whether to return only _SUM columns (e.g. not _AVG)
	:return:
	"""
	logger.debug('Reading aggregated score data: {}'.format(loc_aggscore))
	df = pd.read_csv(loc_aggscore, sep='\t', index_col=['sampleset', 'IID'], converters={"IID": str}, header=0)
	if onlySUM:
	df = df[[x for x in df.columns if x.endswith('_SUM')]]
	rn = [x.rstrip('_SUM') for x in df.columns]
	df.columns = rn
	return df

I think my last commit solves it
