analysis file permissions - set open

[CBroz1]

Is your feature request related to a problem? Please describe.

We previously decided as a lab to open up analysis file permissions, and ran chmod -R 777 on this directory, but this doesn't impact new files, and needs to be rerun occasionally

Describe the solution you'd like

To reflect this for decision for new files, we need to edit

spyglass/src/spyglass/common/common_nwbfile.py

Lines 234 to 236 in dbae127

	# change the permissions to only allow owner to write
	permissions = stat.S_IRUSR | stat.S_IWUSR | stat.S_IRGRP | stat.S_IROTH
	os.chmod(analysis_file_abs_path, permissions)

And publish release notes detailing the chmod approach as a transition mechanism

Describe alternatives you've considered

Manual running of chmod whenever issues arise let's other labs decide how to set up file permissions individually.
