Update the loadFry function

[an-altosian]

Hi @mikelove , here is Dongze using my Altos's GitHub account.

I added two things to the loadFry function:

1. I added the logic for taking a multi-line barcode file. This reflects the changes in the latest simpleaf when processing spatial data.
2. I added the logic for taking a gene id to name mapping file so that the users do not need to do this manually or through some libraries.

Best,
Dongze
