earthaccess.download() ignores errors

[mfisher87]

We found the pqdm library is the thing swallowing all the error messages. pqdm has an exception_behavior option, which defaults to "ignore", surprisingly. The other two settings, "deferred" and "immediate", are both good options for earthaccess.

@chuckwondo and I agree "immediate" is the most intuitive default, and we can establish a new flag fail_fast: bool = True to override it to "deferred" by passing download(..., fail_fast=False). Prior discussion in #36. Please continue discussion here :)

I feel exposing the "ignore" behavior isn't necessary because the user can do their own exception handling with try.

Thoughts?
