https://github.com/acquaman/acquaman/issues/865

New:
   - created a BioXAS tool suite, which contains the existing BioXAS Shutter tool and the new BioXAS Motor tool
   - create BioXAS motor tool to display the status of motors for master/side/imaging beamline of BioXAS
   - added `BioXASMAXvNMotor` to display the `CW`, `CCW` limit information
   - added `MAXvMotorControlEditor` which extends `AMExtendedControlEditor` to be able to display the CW/CCW information

Altered:
 - move the existing BioXAS Shutter tool to the new created BioXAS tool suite
 - modified `CLSMAXvMotor` to be able to handle PV with different units (the default unit is `:mm`)
