feat: Add HTML minification for rendering

[alwismt]

The function has been added to minify the HTML data into a token stream, and then write the minified HTML to a buffer. This feature improves performance by reducing the size of the HTML output.

Description

Added minify.go file with a htmlMinify function that can be used to minify HTML data. Also wrote a test case TestHtmlMinify in minify_test.go to ensure it works as expected. Added the htmlMinify function to Ctx.Render function in Ctx.go and also added an EnableHTMLMinify app config option for it. Wrote another test function Test_Ctx_RenderWithMinify in Ctx_test.go to test rendering with minification enabled.

Interesting and good feature,
Thanks for the work

Can we modify it a bit, currently the feature only looks at the render method, but could be applied to all responses which matched certain content types

I have a middleware in mind that you can add like the compress middleware and then you can configure it to enable different minification on the different routes.

Maybe we should also provide this in the contrib repository, as I don't want to bloat the core (if it's a middleware, we can vote and move the code)

Great, sounds like a good plan. I'll work on implementing this feature in the compress middleware so that it can minify other content types beside HTML.

Additionally, I can create a separate middleware for minification, which can be configured to enable different minification on different routes.

Regarding the contrib repository, that's a great idea as well. We can move the code to the contrib repository if it's agreed upon by the community. Thank you for your feedback and suggestions.

here you misunderstood something, i meant the compress middleware you can use as a template
the actual compress middleware should not be adapted of course

Got it, I will use the compress middleware as a reference and will create a new middleware for minification of different content types.
