Class for structuring a simple value. Unassigned or reserved simple values are emitted as an instance of this class during decoding. This allows an application to handle custom decoding in the reviver function of the decoder.

const { buffer } = new Uint8Array([0x81,0xf8,0x64])
const decoded = decode(buffer, (key, value) => {
  // Let's pretend that a simple value of 100 stands for JavaScript NaN
  if (value instanceof SimpleValue && value.value === 100) return NaN
  return value
})
console.log(decoded) // Expect: [ NaN ]

Simple values can alsoe be encoded.

const example = [NaN]
const encoded = encode(example, (key, value) => {
  if (Number.isNaN(value)) return new SimpleValue(100)
  return value
})
console.log(new Uint8Array(encoded)) // Expect: Uint8Array(3) [ 129, 248, 100 ]
