Pull Request Overview

This PR adds support for remote connection parameter request replies in Bluetooth LE by implementing two new HCI commands and their associated parameters. The changes enable hosts to respond to connection parameter requests from remote devices, either accepting with new parameters or rejecting with a reason code.

• Added enum for connection parameter rejection reasons
• Implemented LE Remote Connection Parameter Request Reply command
• Implemented LE Remote Connection Parameter Request Negative Reply command

The enum should include documentation explaining what this rejection reason means and when it should be used, following the pattern of other enums in the codebase.

Suggested change

	enum RemoteConnectionParamsRejectReason {
	enum RemoteConnectionParamsRejectReason {
	/// The connection parameters provided by the remote device are unacceptable.
	/// This rejection reason should be used when the local device cannot accept the proposed connection parameters,
	/// such as interval, latency, or timeout values, due to policy or resource constraints.

The Duration type parameters (1_250, 10_000, 625) should be documented to explain what these time units represent (microseconds, milliseconds, etc.) for better API usability.

Suggested change

	interval_min: Duration<1_250>,
	interval_max: Duration<1_250>,
	max_latency: u16,
	supervision_timeout: Duration<10_000>,
	min_ce_length: Duration<625>,
	handle: ConnHandle,
	/// Minimum value for the connection interval, in units of 1.25 ms.
	interval_min: Duration<1_250>,
	/// Maximum value for the connection interval, in units of 1.25 ms.
	interval_max: Duration<1_250>,
	max_latency: u16,
	/// Supervision timeout for the connection, in units of 10 ms.
	supervision_timeout: Duration<10_000>,
	/// Minimum connection event length, in units of 0.625 ms.
	min_ce_length: Duration<625>,
	/// Maximum connection event length, in units of 0.625 ms.
