Hendrik van Wyk b3245aba9b No longer use RAM value scale signedness for info frames.
The signedness calculated along with the RAM value scale and offset was
incorrectly applied to the info frame value. This caused some values to
be interpreted as unsigned instead of signed leading to negative values
reporting as very large positive values.
