[pipelines] Convert SDCard to Camera API

[sneakers-the-rat]

Convert miniscope_io.io.SDCard to a SDMiniscope subclass of Camera

• Create SDCard source
  • Parent class FileSource
  • Designate sources as "push" vs "pull" to differentiate from streaming sources - streaming sources "push" data constantly as it is produced, "pull" sources assume the data is static and request it as the consumers need it
• Create Generator sink to be able to iterate over the outputs of a pipeline
• Implement abstract methods on Camera and Device
• Adapt Config
• Update notebooks
