[glrs]

This pull request includes changes to the lib/realms/smartseq3 module to improve the handling of samples, specifically excluding aborted samples from processing. The most important changes are the removal of the aborted sample handling logic and the update to the sample extraction process.

Improvements to sample handling:

• lib/realms/smartseq3/ss3_project.py: Updated the extract_samples method to exclude aborted samples entirely from the list of SS3Sample instances. Added logging to indicate when a sample is skipped due to being aborted. [1] [2]

Code simplification:

• lib/realms/smartseq3/ss3_sample.py: Removed the aborted parameter from the SS3Sample constructor and the associated logic that set the sample status to "aborted". [1] [2]
