IndexOutOfRangeException when parsing some rules

[Sergio0694]

Hi,
I've noticed that the AbpFormatRuleParser.ParseAbpFormattedRule API is throwing an IndexOutOfRangeException when parsing some rules.
In particular, I've noticed the crash when parsing this line from the EasyList Privacy ruleset (https://easylist.to/easylist/easyprivacy.txt):

@@||adobedtm.com^*/satelliteLib-$script,domain=|absa.co.za|argos.co.uk|collegeboard.org|crackle.com|crimewatchdaily.com|directline.com|fcbarcelona.com|jeep.com|laredoute.co.uk|laredoute.com|lenovo.com|lowes.com|mastercard.us|mathworks.com|monoprice.com|nbcnews.com|newyorker.com|oprah.com|pnc.com|realtor.com|redbull.tv|repco.co.nz|searspartsdirect.com|smooth.com.au|sonycrackle.com|stuff.co.nz|subaru.com|timewarnercable.com|trip-planner.australia.com|vanityfair.com|wired.com

I can work around it by using a try/catch block around all the calls to ParseAbpFormattedRule for now, although that's not ideal as it introduces some overhead.

Hope this helps, keep up the good work! 😊

EDIT: on second thought, I think I'll keep the try/catch block in place just to be extra sure, so that I won't get any crashes even if the ruleset changed in the future. Still though, it might be a good idea to have the lib properly handle at least this particular case, now that we've found it.

Thanks for reporting. I'll get to this next week.
