fix: recompile parent template automatically when child template is changed

Hello,

This fix #19

I tried to make it compatible with custom delimiters but I can't guaranty it.

It could serve as a base for a solution to EJS v3, as we could fetch the import content and replace it at build, instead of runtime.

Also, the tests seem broken.

Have a nice day

Hi, any information regarding a merge ?
