Bithelper

**Created a bithelper class to convert everthing from/to bits and bytes**


To convert to bits/bytes
```cs
var canvas   = factory.GenerateRandomCanvas();
bool[] bits  = canvas.AsBitArray();
byte[] bytes = canvas.AsByteArray();
```

To convert to canvas
```cs
var canvas = bits.AsCanvas();
var canvas = bytes.AsCanvas();
```

Bits to bytes (and vice-versa)
```cs
bits.AsByteArray();
bytes.AsBitArray()
```

ToString methods
```cs
bits.toBitString();
bytes.toByteString();
```
