0b5e98591e refactor: prepend a header to each WebTransport chunk 
This commit updates the format of the header added in [1], in order to
match the format used for a WebSocket frame ([2]).

Two advantages:

- small payloads only need 1 byte instead of 4
- payloads larger than 2^31 bytes are supported

6142324fa6 feat: prepend a header to each WebTransport chunk 
WebTransport is a stream-based protocol, so chunking boundaries are not
always preserved.

That's why we will now prepend a 4-bytes header to each chunk:

- first bit indicates whether the payload is plain text (0) or binary (1)
- next 31 bits indicate the length of the payload

351ba8245b fix: properly encode empty buffer in base64 encoding (#131) 
An empty buffer was encoded into `bundefined` instead of `b`
(reproduced on Chrome v108 / Ubuntu).

6d7dd76130 fix: respect the offset and length of TypedArray objects 
The parser now returns the TypedArray object instead of the underlying
array buffer, so its offset and length are now taken in account (which
is the behavior of the classic WebSocket implementation).

Notes:

- this was already the case for the Node.js implementation

- in v3, the TypedArray object was always converted to an array buffer
because a byte was added at the beginning ("message" type)

- we could also have used "data.slice().buffer", but it would have
resulted in the copy of the buffer

cab7db0404 feat: implement the version 4 of the protocol 
See https://github.com/socketio/engine.io-protocol for the list of
changes.

Note: The 'base64-arraybuffer' dependency must now be explicitly
included by the client (not needed by the server).

a947ae59a2 feat: remove packet type when encoding binary packets 
Only packets of 'message' type can contain binary data, so it makes sense to remove the prefix in
order to avoid the concatenation of the packet type.

Breaking change: the packet containing binary data will now be sent without any transformation

Protocol v3: { type: 'message', data: <Buffer 01 02 03> } => <Buffer 04 01 02 03>
Protocol v4: { type: 'message', data: <Buffer 01 02 03> } => <Buffer 01 02 03>

292c00c183 [fix] Encode string payloads as strings even if binary supported (#85) 
This reverts commit 44c7aa5, which caused string payloads to be encoded
as binary (so that huge string payloads were needlessly UTF-8-encoded).

44c7aa5ab9 Fix parse error 
We always need to send binary when encoding payloads when sending from
server to client, because the polling transport has to know the response
type ahead of time.
