Improve falcon intregration

Description

This MR improves the integration of dxp devices (i.e. Falcon, xMAP and Mercury). A minor fix in the device_server was needed since components with lazy=True attribute created a raise condition in the get_device_info(). A pending MR fixes this issue (bec!877).

Type of Change

• changed Kind attributes for rois of EpicsMCARecord
• added input/output_count_rate to EpicsDXPFalcon
• added _default_read_attr and _default_configuration_attr to Falcon, xMAP and Mercury; children inheriting from these classes may be initiated like this:

from ophyd_devices.devices.dxp import EpicsDXPFalcon, EpicsMCARecord, Falcon

class FalconControl(Falcon):
    """Falcon Control class at SuperXAS. prefix: 'X10DA-SITORO:'"""

    _default_read_attrs = Falcon._default_read_attrs + (
        "dxp1",
        "mca1",
    )
    _default_configuration_attrs = Falcon._default_configuration_attrs + (
        "dxp1",
        "mca1",
        )
    # DXP parameters
    dxp1 = Cpt(EpicsDXPFalcon, "dxp1:")
    # dxp2 = Cpt(EpicsDXPFalcon, "dxp2:")
    # MCA record with spectrum data
    mca1 = Cpt(EpicsMCARecord, "mca1")
    # mca2 = Cpt(EpicsMCARecord, "mca2")
