Remove hardcoded compression type and add python-snappy package

[shchen-idmod]

This PR is fixing following 2 issues:

1. Write function will fail if dtk content is too big with lz4 compression
   

   emod-api/emod_api/serialization/SerializedPopulation.py

   Line 75 in 99896c1

   def write(self, output_file: str = "my_sp_file.dtk"):

2. Missed required python-snappy lib when dtk file is great than certain value (repro it with sif file which contain emod-api):

UserWarning: Snappy [de]compression not available.

I think the reason compression type switching between lz4 and snappy is due to this:

By removing the hardcoded compression type in the write function, it will respect the original compression type in the DTK content
