Go Modules URI incorrectly parsed as mailto link

Similar to #82, Go modules are incorrectly rendered as mailto links.

Given a module like golang.org/x/net@v0.0.0-20210326060303-6b1517762897, it is rendered as:

golang.org/x/net@v0.0.0-20210326060303-6b1517762897 mailto:golang.org/x/net@v0.0.0-20210326060303-6b1517762897

It'd be nice if there was an option to disable mailto links for a given regular expression, or all together.

Looking into what it would take to implement this, it looks like mailto: is added here:

glamour/ansi/elements.go

Lines 229 to 231 in ea72398

    
           if n.AutoLinkType == ast.AutoLinkEmail && !strings.HasPrefix(strings.ToLower(u), "mailto:") { 
        
           	u = "mailto:" + u 
        
           }

We can add additional options for the ANSI renderer's context here:

glamour/ansi/renderer.go

Lines 17 to 23 in ea72398

    
           type Options struct { 
        
           	BaseURL          string 
        
           	WordWrap         int 
        
           	PreserveNewLines bool 
        
           	ColorProfile     termenv.Profile 
        
           	Styles           StyleConfig 
        
           }

	if n.AutoLinkType == ast.AutoLinkEmail && !strings.HasPrefix(strings.ToLower(u), "mailto:") {
	u = "mailto:" + u
	}

	type Options struct {
	BaseURL string
	WordWrap int
	PreserveNewLines bool
	ColorProfile termenv.Profile
	Styles StyleConfig
	}
