  .SYNOPSIS

  Converts a PVE disk-size value such as '32G', '512M' or '4M' to bytes.

  .DESCRIPTION

  The suffix is K, M, G or T in powers of 1024; a number without a suffix is bytes. This is the format of

  the size= option PVE writes into disk and volume entries, and of the resize endpoints' size parameter

  (whose schema pattern is \+?\d+(\.\d+)?[KMGT]?). Returns $null for anything else.
