strip superfluous spaces from class lists

[romshark]

Consider the following snippet from a templ template:

<div
	class="
		flex w-full h-full
		justify-center items-center
		hover:bg-blue-50
	"
>

I often follow this styling to avoid putting very long lists of classes in a single line:

<div
	class="flex w-full h-full justify-center items-center hover:bg-blue-50"
>

The length of real class lists in my code is often several times longer.

templ v0.3.833 generates the following Go code:

<div class=\"\n\t\t\t\t\t\t\tflex w-full h-full\n\t\t\t\t\t\t\tjustify-center items-center\n\t\t\t\t\t\t\thover:bg-blue-50\n\t\t\t\t\t\t\">

I believe these line-breaks and tabs serve no purpose and can be stripped.

• This would reduce the size of the generated HTML at runtime.
• ...and make generated code smaller and easier to read.

<div class=\"flex w-full h-full justify-center items-center hover:bg-blue-50\">

Seems like a straightforward change to introduce, and I can't think of any issues that could be caused by doing it...
