Encode attachments

const { AttachmentMSTTransfer } = require('./lib')

const attachment = new AttachmentMSTTransfer(
      'MVS.HUG',
      1,
    )

console.log(attachment.toBuffer())
// <Buffer 01 00 00 00 02 00 00 00 02 00 00 00 07 4d 56 53 2e 48 55 47 01 00 00 00 00 00 00 00>

Decode attachments

console.log(Attachment.fromBuffer(Buffer.from('010000000200000002000000074d56532e4855470100000000000000', 'hex')))
