Function getPointFormat4

getPointFormat4(
    reader: Reader | DataView<ArrayBufferLike>,
    header: LASHeader,
    offset?: number,
    littleEndian?: boolean,
): VectorPointM<LASFormat0_5>
Reads a point using the Point Data Record Format 4 https://github.com/ASPRSorg/LAS/wiki/Waveform-Data-Packet-Descriptors-Explained
Parameters
- reader: Reader | DataView<ArrayBufferLike>
  data reader, works like a DataView
- header: LASHeader
  las header
- offset: number = 0
  where to start reading in the point data
- littleEndian: boolean = true
  endianess. Defaults to true (LAS always LE but LAZ may have BE)
Returns VectorPointM<LASFormat0_5>
- The parsed point with Format 4 metadata
