Decrease smoothing parameter default value

[skushneryuk]

In most known to me applications of tqdm progress bar using lower smoothing value seems to be more appropriate, especially w.r.t. estimate of total time of execution. Cases when higher value of smoothing is necessary are either rare or almost non-existent

Hence, I propose to change default value to something that better corresponds to general use case (e.g. smoothing=0.1 or even smoothing=0.01

I've been using tqdm for years and have only ever seen the estimated time be useless since it jumps around wildly. I actually only learned of this option today, just figured it was a tqdm limitation (that's on me for not reading docs more carefully, but I bet a lot of other folks just write off the estimate).

I've never had a use case where I needed it adapt so aggressively instead of just taking average time.

I would even propose a default of smoothing=0 to make it clean and clear.

Incidentally in tqdm>=4.66 you can export TQDM_SMOOTHING=0.1 in your .bashrc or equivalent (#1491)
