Replace current selfcal gain plotter with cubical gain plotter

[Athanaseus]

Running the cubical gain plotter:

plot-gain-solutions -o de_solutions_bp_D1_ap -B --dir 1 --nrow 6 --ncol 10 --diag ap g_phase-dE-field_0-ddid_None.parmdb

import stimela

INPUT = 'input'
OUTPUT = 'output'
MSDIR = 'msdir'

TABLE = 'g_phase-dE-field_0-ddid_None.parmdb'

stimela.register_globals()

recipe = stimela.Recipe('Plot Gain Solutions', ms_dir=MSDIR, JOB_TYPE="singularity")

recipe.add('cab/cubical_pgs', 'plot_gains',
        {
            "files" :   "%s:output" % TABLE,
            "output-name" :  TABLE.rsplit('.', 1)[0],
            "dir" :   1,
            "bandpass" :   true,
            "diag"  :   "ap",
            "nrow" :   6,
            "ncol" :   10,
        },
            input=INPUT,
            output=OUTPUT,
            label='plot_gains:: Cubical')

recipe.run()

@Athanaseus could you please post an updated set of gain plots (after the fix)

[Athanaseus]

Setting enabling gain_plot will produce the following plots:

selfcal:
  enable: true
  img_npix: 1800
  img_cell: 2
  cal_timeslots_chunk: 240
  cal_cubical:
    gain_plot:
      enable: true

This example is from the Jenkins tests:

1. mypipelinerun-g-phase-gains-1-1532022061_subset-circinus_p3-corr-G

2. mypipelinerun-g-phase-gains-1-1532022061_subset-circinus_p3-corr-B

3. mypipelinerun-g-amp-phase-diag-gains-2-1532022061_subset-circinus_p3-corr-G

4. mypipelinerun-g-amp-phase-diag-gains-2-1532022061_subset-circinus_p3-corr-B

NB: The plots feature antenna amplitude and phase in a single plot with twin y-axes respectively.
