Deploy blueapi and run with a grid scan with a diode

need to call the scan from api with a scanspec string that describes the grid trajectory.

need to supply the diode device

from @iain-hall 's notes:

Beamline script : /dls_sw/i18/scripts/beamlinestuff/I18Scans/Create_deg_Lookuptabledcm.py
Old version of beamline script in GDA : scripts/create_lookuptable_deg.py
Procedure is as follows :
Adjust undulator gap to using current lookup table for initial Bragg angle
Scan across desired range of Bragg angles, for each angle :
Scan undulator gap (current gap value ± small range) and measure on d7bdiode (Diode PV is BL18I-DI-PHDGN-07:B:DIODE:I)
Find undulator gap that gives peak d7bdiode value (fit gaussian curve, store peak position).
Fit quadratic curve to the set of Bragg angle - undulator gap values. These values are used to generate the lookup table of undulator gap vs. Bragg angle.
Scan is currently done by GDA using Jython; quadratic curve fit is done using IDL.
Undulator gap scans are are carried out at each harmonic.
Beamline staff manually update the lookup table - copy-pasting updated section (i.e. values for a range of bragg angles) into text file to replace old values.
