Enhancement request for script dir and error logging

[aweaver1fandm]

Use case:
We have created a conda environment for birdnet which sits in our /opt directory. We have permissions set
for conda environments so that regular users can't write to that directory because we've had issues in the past with folks destroying the environments (many of which are shared among multiple users).

In this setup we are not able to run birdnet because utils.py and config.py(and possibly other things) hard code error and script directories to be where the script is installed resulting in the following set of errors:

Missing BirdNET_GLOBAL_6K_V2.4_Model/variables/variables.data-00000-of-00001

We would like these to either be set via a command line option or if they have to hard coded, perhaps hard coded to somewhere like /tmp
