[issue-2557] Add :from-:to range route formats

[ProgrammingMuffin]

Implements this feature (https://github.com/labstack/echo/issues/2557)

Adds :from-:to route.

example /flights/:from-:to

This is little bit too simple take for implementing this feature. I would say that the requirement we are talking is allowing multiple parameters per route segment where segment is string part between / (slashes). Searching for param end to be / or - is little bit too restricted. Probably using syntax "/{month}-{day}-{year}" like Chi uses would be better.

p.s. using new special characters in route paths like { and } (or whatever character pair is selected) potentially breaks small number of users applications.

@aldas Thank you for your comment.

the / delimiter was already present and I don't think we should change that.

If I understood correctly, the restriction here is that users cannot use - in a parameter name like :user-name. Is that correct?

No, using only - is too restricting.

Sorry, I did not word this clearly. What I meant is that in addition to :param we could support {param} syntax and in that case we can have anything between two params like {file}.{ext}. As long there is something between that we can distinguish as separator.

@aldas Hi, can this PR be merged? The {} placeholder format is very good. Some frameworks in other languages ​​also use this approach For example: https://laravel.com/docs/11.x/routing#required-parameters
