sendMessageBinary throws "TypeError: Buffer expected" when using with Bun

[mertushka]

Environment:

• Bun version: 1.1.42
• node-datachannel version: 0.23.0

Issue:
When using the sendMessageBinary method with a ArrayBuffer, a TypeError: Buffer expected is thrown, even though a Buffer is passed to the method. This issue seems specific to Bun, with using Node it works flawless.

> bun index.ts

data to send: Uint8Array(10) [ 0, 8, 63, 225, 66, 235, 13, 167, 86, 217 ]
159 |       data.arrayBuffer().then((ab) => {
160 |         __privateGet(this, _dataChannel).sendMessageBinary(new Uint8Array(ab));
161 |       });
162 |     }
163 |     else {
164 |       __privateGet(this, _dataChannel).sendMessageBinary(new Uint8Array(data));
                                             ^
TypeError: Buffer expected
at send (\node_modules\node-datachannel\dist\cjs\polyfill\RTCDataChannel.cjs:164:40)

Expected Behavior:

node-datachannel/src/cpp/data-channel-wrapper.cpp

Line 193 in d5b82ef

if (length < 1 || !info[0].IsBuffer())

This condition would pass successfully.

Workaround:

node-datachannel/src/polyfill/RTCDataChannel.ts

Line 180 in d5b82ef

this.#dataChannel.sendMessageBinary(new Uint8Array(data));

Using Buffer.from(new Uint8Array(data)) resolves the issue.

Additional Context:
The problem seems to stem from how the method checks for Buffer in the C++ code (TrackWrapper::sendMessageBinary).
