Out of date CAMB

When trying to run the ACT DR6 pipeline in /projects/ACT_DR6, I was met with the following error:

pspipe-run -p yaml/pipeline_dr6.yml
Traceback (most recent call last):

CAMB was recently updated to version 2.0.0 and takes lens_output_margin as the key instead of lens_margin. Updating the accuracy_params in global_dr6v4_bin50.dict fixed this issue.

Start with the accuracy_params in global_dr6v4_bin50.dict and compare its CAMB parameter name with the installed CAMB 2.0.0 interface. Update the outdated key, then rerun pspipe-run -p yaml/pipeline_dr6.yml in /projects/ACT_DR6; done means the pipeline no longer raises CAMBUnknownArgumentError for lens_margin.
