Issue Log:
Error: The value, "40℃", in ["CHROMATOGRAPHY"]["COLUMN_TEMPERATURE"] should be a number or range (ex. "5-6") followed by a space with a unit (ex. "5 V") from the following list: ['°C', 'C']. Ignore this when more complicated descriptions are required.
Error: SUBJECT_SAMPLE_FACTORS section missing sample ID(s). The following IDs were found in the ["MS_METABOLITE_DATA"]["Data"] section but not in the SUBJECT_SAMPLE_FACTORS:
	""
Warning: The "Formula" column at position 2 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "formula", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:

Warning: The "CAS ID" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "cas_number". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name.
Warning: The "CAS ID" column at position 5 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "cas_number", and some of the values in the column do not match the expected type or format for that column. The non-matching values are:

Warning: The "RT" column at position 4 in the ["MS_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "retention_time". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name.
Error: Column(s) with no name were found in the ["MS_METABOLITE_DATA"]["Data"] table.
Warning: The "" column at position 42 in the ["MS_METABOLITE_DATA"]["Data"] table has all null values.
