Mdlink encoding

[YauhenPylAurea]

Continuation of #338

There are 2 issues in the PR that an advise is needed :) Could you please help me with that? Thank you in advance for the help.

1. Encode func is used from mdurl. It is archived repository without activity. And it seems only encode functionality is required to fix the original issue. So the code was copy-pasted. Would it be better to import the whole mdurl package instead of the selected approach?

2. Existing test TestOutput has been updated to check the case with a space in a table name. Would it be better to create a completely separate test for such case?

Thank you.

@YauhenPylAurea Thank you!!!!

Would it be better to import the whole mdurl package instead of the selected approach?

Yes, tbls uses gocredits to generate CREDITS. I think it is a good idea to use mdurl as a package to follow that mechanism.
It is also meant to honor that package.

Also, it looks like mdurl is moving to the following repository.

https://gitlab.com/golang-commonmark/mdurl

Would it be better to create a completely separate test for such case?

More test cases are welcome. However, I believe the tests you have modified and added this time are enough.

@k1LoW thank you for the review.

Copy-pasted code has been replaced by using mdurl package directly as per your advise. Thanks!
