Parser allows invalid format of temperature group #136
Description
The regex for the temperature group allows an arbitrary number (but at least 1) of digits, both for temperature and dewpoint:
Lines 87 to 90 in 96f6b98
However, the Manual on Codes gives the format of the temperature group as T'T'/T'dT'd in 15.11, calling for exactly 2 digits.
Consequently, the following report should raise an error instead of parsing a temperature of 201°C (which clearly is a typo in this context considering the reports before/after this one).
