panic when forging endorsement

[utdrmac]

Simplest example:

package main

import (
  "fmt"
  "github.com/goat-systems/go-tezos/forge"
  "github.com/goat-systems/go-tezos/rpc"
)

func main() {

    endorsement := rpc.Endorsement{
        Kind: rpc.ENDORSEMENT,
        Level: 12345,
    }

    endorsementBytes, err := forge.Encode("BKxWMXLfmd7RmT4xTyF9wpeMeiq1H4mw4RnruY9kBxkzCQKieqD", endorsement.ToContent())
    if err != nil {
        panic(fmt.Sprintf("ERROR: %s", err.Error()))
    }

    fmt.Println("Bytes:", endorsementBytes)
}

Result:

$ go run test.go
panic: runtime error: slice bounds out of range [:4] with capacity 1

If the purpose is to create a BigEndian representation of the level, can you use this? https://play.golang.org/p/xf1nYhprdmu

func forgeInt32(value int, l int) []byte {
    bigE := make([]byte, 4)
    binary.BigEndian.PutUint32(bigE, uint32(value))
    return bigE
}

I modified my fork to use the above and it appears to be working as expected.

Great, thanks again @utdrmac!

Fixed in V4. Thanks again!
