As we can construct a bitset object by a Buffer, Can we convert the bitset to Buffer

let bitset = require("bitset");
let buf = Buffer.from([100, 97, 98]);
let bs = bitset(buf);
bs.toString();
'11000100110000101100100'

Can we convert a bitset into buffer?
let bs1 = new bitset();
bs1.setRange(4,9,1);
{ data: [ 1008, 0, 0, 0, 0, 0, 0, 0, 0, 0 ], _: 0 }
bs1.toString();
'1111110000'

Now can this be converted into the buffer?
eg. add the padding 0's left and make it's size multiple of 8 then convert to byte array or Buffer.
