Further enhancements to daily Lasso

This PR implements a bugfix and several formatting enhancements for daily-lasso:

• Fix a bug in navbar construction
• Read in 10 minutes of auxiliary data and remove all flat channels up-front, before launching gwdetchar-lasso-correlation
• Drop locally defined functions for HTML table formatting, and use a combination of keyword arguments and lambda functions instead
• Reduce check_call timeout condition back to half an hour
