bug: Inconsistent casing with parsed structs

[mrueg]

Describe the bug

If my struct has a field that is not all lower case and I render it in a template using sprout, the field will return as lower keys.
The only option I have is to use annotate the field using go tags, which might not always be feasible.

To Reproduce

Use minimal example provided below, there are two structs, one with the go tag and one without.

Expected behavior

It should preserve the casing of the field name.

Code Snippet

package main

import (
	"fmt"
	"os"
	"text/template"

	"github.com/go-sprout/sprout/sprigin"
)

type apple struct {
	CamelCase int
}

type pear struct {
	CamelCase int `yaml:"CamelCase"`
}

func main() {
	myA := apple{CamelCase: 5}

	myB := pear{CamelCase: 10}
	tpl := template.Must(
		template.New("example").Funcs(sprigin.FuncMap()).Parse(`{{ . | toYAML }}`),
	)
	tpl.Execute(os.Stdout, &myA)
	fmt.Println("")
	tpl.Execute(os.Stdout, &myB)
}

This returns:

camelcase: 5
CamelCase: 10

I would have expected:

CamelCase: 5
CamelCase: 10

Hi @mrueg,

I will check to understand the case correctly and found the root cause if related to sprout itself !

Thanks for reporting
