Add a wind speed filter in step1_generate_emission_scenarios.ipynb

[maverickjia]

This update introduces a filter in step1_generate_emission_scenarios.ipynb to exclude invalid wind speed values. Specifically, a lower bound (ws_lb) and an upper bound (ws_ub) have been set to define the acceptable range for wind speed values.

@maverickjia the spell check linter flagged these issues (you can also inspect if you look at the checks output):

Can you verify that these terms are correct, and if not, please correct the spelling? Thanks!

I've corrected some of the typos. However, I couldn't locate these 3 errors in step 1 code: ./demo/step1_generate_emission_scenarios.ipynb:237: fo ==> of, for ./demo/step1_generate_emission_scenarios.ipynb:237: OpeG ==> open ./demo/step1_generate_emission_scenarios.ipynb:237: Ba ==> By, be

I couldn't either. What I think it is, is in those extremely long num-char strings that are unfortunately unique to jupyter notebooks, it detected some odd combination of characters. As long as you've had a look and the code is correct, that's the most important thing. Thanks! Merged.
