this seems to cause a deadlock when generating the last sequence (4/4 in this case. 1~3 works fine but 4 fails):

...
zzu
zzv
zzw
zzx
zzy
zzz
fatal error: all goroutines are asleep - deadlock!

goroutine 1 [select]:
(...)/brutedict.(*BruteDict).Id(0xc00011c3c0, 0xc000006018, 0xc00012df48)
        (...)/brutedict/brutedict.go:59 +0x89
main.main()
        (...)/main/main.go:23 +0x189
exit status 2

this seems to fix the deadlock:

n := bytes.IndexByte(b, 0) // IndexByte returns -1 if no null bytes where found
if n > 0 {
    bd.queue <- string(b[:n])
} else {
    bd.queue <- string(b)
}
