Map str2num does not seem do anything with pyton 3 to ms sql server

[yozgoesdigital]

When running the export tool and use map via str2num it does not seem to do anything. Also changed data type van varchar to NUMERIC on database side, but the tool changes the column type back to TEXT:

2019-01-07 15:47:06,718 commcare_export.writers WARNING Altering column cc_waste_intake.quantity from NUMERIC(18, 0) to TEXT for value: "<class 'str'>:7.45"

adding "--strict-types" in CLI command could be used as a workaround
