MapTo cannot parse values as uint8

[rolandjitsu]

Describe the bug Parsing the following:

[mysection]
mykey=90

When using MapTo results in:

set field "mykey": unsupported type "uint8"

If the type is uint8:

type MySection struct {
	MeyKey uint8 `json:"mykey" ini:"mykey"`
}

To Reproduce Just load the config and use MapTo:

cfg, _ := ini.Load([]byte(`
[mysection]
mykey=90
`))
mySec := &MySection{}
err := cfg.Section("mysection").MapTo(mySec)

Expected behavior MapTo should be able to parse values as uint8.

Here's where the problem might lie If you can, I suggest you switch to uint16 or a larger uint :smile:

That's what I did. Does the lib parse byte arrays? I wonder why that comment is there.

My guess :disappointed_relieved:

All values loaded in the ini are considered to be strings, if by default 1 string character is a byte, if a non-ASCII character is encountered it will not be parsed to a byte or will be lost

// String of length 1

"a" = [97] index 0 = 97 // Englische
"α" = [206, 177] index 0 = 206 or 0? // Greek
"啊" = [229, 149, 138] index 0 = 229 or 0? // Chinese
