New step size warning shows spuriously

[MialLewis]

Describe the bug The new step size warning tends to come up on most occasions when running scripts - I guess there's some rounding issues.

WARNING:root:The |Q| step provided (0.0467) is smaller than the data step in the workspace (0.0467). Please provide a larger |Q| step. Also, this warning is shown as an error.

To Reproduce Run this script from the mantid script editor. changing the file paths:

# Python Script Generated by Mslice on 2023-05-17 16:56:25
import mslice.cli as mc
import mslice.plotting.pyplot as plt

ws_MAR21335_Ei60meV = mc.Load(Filename='C:/Users/wym92549/Downloads/mslice data\MAR21335_Ei60meV.nxs', OutputWorkspace='MAR21335_Ei60meV')

fig = plt.gcf()
fig.clf()
ax = fig.add_subplot(111, projection="mslice")
cut_ws_0 = mc.Cut(ws_MAR21335_Ei60meV, CutAxis="|Q|,-5.0,5.0,0.04671", IntegrationAxis="DeltaE,0.0,10.0,0.0", NormToOne=False, IntensityCorrection=False, SampleTemperature=None)
ax.errorbar(cut_ws_0, label="MAR21335_Ei60meV 0.00<E<10.00", color="#1f77b4", marker="o", ls="-", lw=1.5)

from mslice.cli.helperfunctions import hide_a_line_and_errorbars, append_visible_handle_and_label
from mslice.util.compat import legend_set_draggable

# hide lines, errorbars, and legends
handles, labels = ax.get_legend_handles_labels()
visible_handles = []
visible_labels = []

append_visible_handle_and_label(visible_handles, handles, visible_labels, labels, 0)

legend_set_draggable(ax.legend(visible_handles, visible_labels, fontsize='medium'), True)

ax.set_title('', fontsize=12.0)
ax.set_ylabel(r'Signal/#Events', fontsize=10.0)
ax.set_ylim(bottom=-10.039915777534894, top=212.87182783248542)
ax.set_xlim(left=0.07009345794392507, right=5.210280373831775)
mc.Show()

Expected behavior Warning does not show when the cut step size is almost equal to the bin width size. If warning does show, do not show as error in workbench.
