Switch `Buffer.from` to use `new Buffer` when used on arrays Buffer.from when used on arrays of integers returns `null` when running with meshagent (at least on linux, not sure if this happens elsewhere). This allows for meshcmd amtider to actually start, since otherwise the connection is just left hanging

Switch `Buffer.from` to use `new Buffer` when used on arrays Buffer.from when used on arrays of integers returns `null` when running with meshagent (at least on linux, not sure if this happens elsewhere). This allows for meshcmd amtider to actually start, since otherwise the connection is just left hanging

function ShortToStr(v) { return new Buffer([(v >> 8) & 0xFF, v & 0xFF]); }
function ShortToStrX(v) { return new Buffer([v & 0xFF, (v >> 8) & 0xFF]); }
function IntToStr(v) { return new Buffer([(v >> 24) & 0xFF, (v >> 16) & 0xFF, (v >> 8) & 0xFF, v & 0xFF]); }
function IntToStrX(v) { return new Buffer([v & 0xFF, (v >> 8) & 0xFF, (v >> 16) & 0xFF, (v >> 24) & 0xFF]); }
Added IDER to MeshCMD, fixed MeshAgent connection exception.
