[v1.0.0] - organize the formats

[johnnv1]

The formats module should contain the code needed to describe the data.

For example, it should contain a CCAgT submodule responsible for loading, modifying, and saving data in CCAgT format.

Also, perhaps submodules for loading, validating and saving data in the formats should be added: COCO and Label Box. You Probably will need to add other private submodules such as annotations and masks.
