Function Bitfield

Bitfield<This, Value>(len, opt?): DecoratorType<This, Value>
@Bitfield decorator define the bit-length of the property it decorates.

The sum of the bit-length declared by the properties decorated with a @Bitfield can exceed 8-bits and may not be aligned byte aligned.
Type Parameters
- This
  The type of the bitfield.
- Value
  The type of the property decorated or the target type the bitfield resolve to.
Parameters
- len: number
  The bitlength of the property it decorate.
- Optionalopt: Partial<BitFieldOptions>
Returns DecoratorType<This, Value>
Example
The top-most property of a class decorated with a @Bitfield decorator will contain the most significant bits (MSB) of the value decoded/encoded. In the example 'field_1' contains the two most significant bits.
```
class BitFieldObject {
  @Bitfield(2)
  field_1: number

  @Bitfield(4)
  field_2: number

  @Bitfield(1)
  field_3: number
}

class Header {
  @Relation(BitfieldObject)
  bitfield: BitFieldObject
}
```
Remarks
The sum of the bit-length declared by the properties decorated with a @Bitfield would result in a 8, 16 or 32bits integer being read. Right now 24 bits bitfields or longer than 32bits are not supported.

Throws
If a Primitive (@Relation) has already been defined inside the bitfield class
