Underlining and Strikethrough don't work at the same time.

(This is an edit, I wrote an issue for another library here, sorry for that)

Hi, firstly I would like to thank you for this great library!

I have found a little bug where text can not be underlined and strikethrough at the same time. I think the problem lies in the fact that they both have the same (ending) symbol which makes parsing really difficult.
I personally fixed this by making strikethrough another symbol ("~~"). To be fair, I just copied the functionally of underlining and when both are needed, I make sure that I use __ ~~{0.25:} or ~~ __{0.25:}, the symbols don't clash anymore and there isn't a problem anymore.
The text is shown as "text that has to be both effects"

I have a screenshot from the easytable library to show the effect.

"Beneath is an example of __underscored__ and __{0.25:}striked through__ \n"
+ " __ __{0.25:}text, both at the same time__ __"
