Multiprecision unique coords detection to __from_ds__

[philipc2]

Closes #318

Overview

Changes to __from_ds function to include multi-precision

Expected Usage

import uxarray as ux

# Provide nodes that are extremely closed to each other
face_nodes_connectivity = [['1.000000000000000000', '1.000000000000000000001', '1.0000000000000000000012'],
 ['1.000000000000000001', '1.000000000000000000002', '1.0000000000000000000013']]

uxgrid =   ux.Grid(face_nodes_connectivity, multi_precision=True, precision= 65,
                        vertices=True,
                        islatlon=False,
                        concave=False)
print(uxgrid.nMesh2_face )# It will still detect two faces without degenration
>>> 2

# Perform any provided grid manipulation and then the results is precise up the the 65 bits

PR Checklist

General

• An issue is linked created and linked
• Add appropriate labels
• Filled out Overview and Expected Usage (if applicable) sections

Testing

• Adequate tests are created if there is new functionality
• Tests cover all possible logical paths in your function
