Bump amphp/amp from 2.1.1 to 2.3.1

[dependabot-preview]

Bumps amphp/amp from 2.1.1 to 2.3.1.

Release notes

Sourced from amphp/amp's releases.

2.3.1

• Fixed TracingDriver not overriding all methods.

2.3.0

• Added TracingDriver to debug (hanging) tests / applications. The environment variable AMP_DEBUG_TRACE_WATCHERS=true can be set to automatically create a TracingDriver wrapping the actual driver. TracingDriver::dump() can be used to dump all enabled, referenced watchers keeping the loop running.

2.2.1

• Fixed backpressure release on Emitter::emit(), the backpressure is now released as soon as the value is consumed, instead of the next value being requested.

2.2.0

• Added CombinedCancellationToken
• Added delay() as shortcut for new Delayed

2.1.2

• Fixed issue where the loop time in NativeDriver was not refreshed after waiting for I/O streams (#256)
• Fixed compatibility issue of NativeDriver with pcntl_async_signals() (#264)
• A custom queue is now used for timers in NativeDriver to allow cancelled timers to be garbage collected immediately instead of after their original expiration time (#220)
• Resolving a promise with an object that throws when destructed will now forward that exception to the event loop error handler (#271)
• Fixed loop time to support 32-bit systems (#252, #273)
