`EcostressDatabase` imports `Instrument` field incorrectly

[MattWenham]

Due to a change in the filename format, EcostressDatabase currently imports the Instrument field incorrectly. The fix would appear to be to change line 197 of ecostress.py to read:

instrument = os.path.basename(f).split('.')[-3]

My apologies, I can't put this into a PR as my employer does not allow me to contribute to Open Source projects 😕

Thanks for the suggested fix. With which version of Ecostress did you encounter this?

Appears to be v1.0, the current version: https://speclib.jpl.nasa.gov/
