Function wrap

wrap<T extends NonNullable<Encodable>>(
F: Constructor<T, []> & Decodable<T>,
overrides?: Partial<StructFieldType<T>>,
): StructFieldType<T>
Turn a TLV class into a field type, where the TLV directly appears as the field.
Type Parameters
- T extends NonNullable<Encodable>
Parameters
- F: Constructor<T, []> & Decodable<T>
- overrides: Partial<StructFieldType<T>> = {}
Returns StructFieldType<T>
Example
Given this structure:
```
Outer = OUTER-TYPE TLV-LENGTH Inner
Inner = INNER-TYPE TLV-LENGTH INNER-VALUE
```
You can define the Outer builder:
```
const buildOuter = new StructBuilder("Outer", TT.Outer)
  .add(TT.Inner, "inner", StructFieldType.wrap(Inner));
```
Inner type must encode itself as a TLV, and its TLV-TYPE must equal field TLV-TYPE.
