Hey! I'd like to request support for bacpac/dacpac extensions. I'm currently unable to use ouch for de/compressing Microsoft's bacpac/dacpac files.

This is my current workaround:

zip -r new_database.bacpac *

instead of ouch

Definition of the file:

File format
A .dacpac is a compressed folder with a .dacpac extension, and similarly a .bacpac is a compressed folder with a .bacpac extension. An advanced user can unpack the file to view the multiple XML sections representing details of the origin, the objects in the database, and other characteristics. To unpack a .dacpac or .bacpac, replace the file extension with .zip and use a file compression utility to unzip the file.
