This is the initial release of Echoregions: A lightweight package designed for processing region and bottom line labels from Echoview, and creating masks on [echopype](https://echopype.readthedocs.io/en/stable/)-generated backscattering data.
Initial Features
- Processing Echoview Line (EVL) and Echoview Region (EVR) Files
- EVL files generally contain both human-annotated and Echoview-annotated depth data
- EVR files generally contain region annotations for different marine organisms and survey logs
- Creating 2D and 3D region masks for echopype-generated Sv datasets based on depth and time values in the EVL and EVR files
- Subsetting, plotting, and saving processed EVL and EVR data
To be included in later releases
- Merging of EVR file data
- Reading of EVL and EVR files from an S3 Bucket
