Updates to smoldyn UI template

[blairlyons]

Problem

In the process of implementing autoconversion for Smoldyn, we identified updates that need to be made to the template files:

• we want to be able to validate the file extension for Smoldyn files during autoconversion
• we want to make it easier to convert data from the front end

Solution

I added a "match" field for smoldyn_data's file_contents with a regex pattern to validate that the path is for a txt file.

Let me know if there's a better way to do this!

Type of change

• New feature (non-breaking change which adds functionality)

Change summary:

• add file extension validation for smoldyn file
• also edited some of the names of parameters to make the JSON structure better align with the structure we expect in FileConverter, allowing us to better reuse code. This involves:
  • changing parameter names from snake_case to camelCase
  • changing box size's key name from box_size to size
  • changing the keys for xyz coordinates from {0,1,2} to {x,y,z}
