Hi, guys,

is there a way to query or flip specific bits?

```
julia> binary = 0b111
0x07
julia> bitstring(binary)
"00000111"
julia> typeof(binary)
UInt8
```

In this case the following results would be expected:

```
binary[1] == binary[2] == binary[3] == 1
```

and for all all N greater than 3 (within half the limits)

```
binary[4] == ... == binary[N] == 0
```

how could I perform such a thing? how could I possibly perform this performant?

thanks.
