Case sensitivity challenges

[kd2eat]

When searching for a sonde via the search box, or entering a sonde by serial number at https://tracker.sondehub.org/nnnnnnnn, please consider making those searches case insensitive. It makes it a lot easier when manually typing a sonde serial number. I pretty much forget every... single... time. Thanks!

All radiosonde serials should be uppercase only, so running .upper() (or JS equivalent) may be a starting point. This won't work for chase cars though.
