feat(itho-wpu): use (hardcoded) datatype from getdatatype in datalog

Browse Source 
Action "getdatatype" returns a list of bytes representing the datatype
for each field in action "getdatalog". This is a subset of these
datatypes:

* 0x0: integer (1 byte)
* 0xc: integer (1 byte)
* 0x10: unsigned integer (2 bytes)
* 0x92: 2 decimal signed float (2 bytes)
