strconv: no way to ParseFloat / ParseInt from []byte #3197
Description
The strconv package's ParseFloat / ParseInt only take string. To reduce allocations, I need to parse an int from a []byte. I attempted to convert strconv's Parse internals to use []byte instead, and then make the existing string versions make an unsafe []byte of the string's memory using reflect.SliceHeader / reflect.StringHeader, but the reflect package already depends on strconv, so there's an import loop.
