Lat/Long values with two direction characters are improperly parsed

[bronwyncombs]

Describe the bug
A clear and concise description of what the bug is.

On a Locality record, a latitude or longitude value with two characters denoting direction (i.e., - and N/S/E/W) (e.g., -157 W) is shown as 157° E when parsed on the form.

Further, conflicting directions are not caught, e.g., -157 E --> -157 W , -50 S --> -50 N

Expected behavior
A clear and concise description of what you expected to happen.

• double directions should be interpreted as if one was present
• conflicting direction characters (e.g., -157 E) should have save blocked

InmakeLatLong() the two signs are multiplied:

const sign = (direction === 's' || direction === 'w' ? -1 : 1) * originalSign;"-157.14015 W"   ->  +157.14015     (both mean west; result is east)"-232'45.1\"S"  ->  +23.045861     (both mean south; result is north)
