A fully typed, zero-dependency and RFC compliant iCalendar / ICS parser

ical-ts's Issues

Non-standard property forces parsing to fail

I'm using the library to parse an ical string from a google calendar public url, while doing so I'm facing some challenges. I'm sure that most of the problems are because either support for the newest spec is missing or google is doing non-standard things.

A property FILENAME on an attachment ATTACH;FILENAME="Some video.mp4";FMTTYPE=video/mp4:https://drive.google.com/file/d/.../view?usp=drive_web

Following your source, I've fixed this by using string replacement to change FILENAME to X-FILENAME. That at least gets me further into parsing. It would be nice to have a lenient parsing option, as someone using your library I just want to have the data parsed, whether the ical is 100% standards conforming bears no meaning on my goal to derive use out of the data there-in.

Second, I also hit a problem where a x-... property (correctly escaped by google) appears multiple times and thus is not converted into a list property automatically. The solution here would be to allow specifying what X- properties are list typed, always treating X- props as lists, or auto-converting to a list when multiple are present.
