Cable delay configuration

[alecandido]

The cable delay, as measured by the time-of-flight experiment, is registered in the AcquisitionConfig configuration

qibolab/src/qibolab/_core/components/configs.py

Lines 89 to 90 in 80bd287

	delay: float
	"""Delay between readout pulse start and acquisition start."""

However, while being related to the physical channel (and certainly not specific to the logical one) this would be just a characterization property as such, and there would be no usage for it in Qibolab (while it is relevant for Qibocal).
Instead, this parameter is actually used during an operation: the measurement. But since the measurement is a native gate, it makes sense to have the cable delay part of its configuration.
In particular, we can make it part of a Readout operation, which already spans both a probe pulse and an acquisition event.
