Function encodeRemainingLength

encodeRemainingLength(value: number): Uint8Array
Encodes an MQTT remaining-length value as a 1-4 byte varint.

MQTT uses a base-128 varint with the high bit of each byte signalling continuation, capping the value at MAX_REMAINING_LENGTH. This is the length prefix on every fixed header and is the most error-prone part of the wire format, so it lives in its own well-tested function.
Parameters
- value: number
  A non-negative integer no larger than MAX_REMAINING_LENGTH.
Returns Uint8Array
The encoded bytes (1-4 of them).
Throws
If value is negative or exceeds the maximum.

Since
1.0.0
Example
```
import { encodeRemainingLength } from 'edgeport/mqtt';

encodeRemainingLength(0); // Uint8Array [0x00]
encodeRemainingLength(127); // Uint8Array [0x7f]
encodeRemainingLength(128); // Uint8Array [0x80, 0x01]
```
