DX import partially fails if invalid PatientSize value

[Ed McDonagh]

(0010,1020) PatientSize is of type DS (Decimal String), ie a Decimal or floating point number.

One vendor has put the string MEDIUM in that field, which is not allowed.

As such, this isn’t currently checked for and prevents the table from being saved.

Propose checking for this value before saving the table.

[Ed McDonagh]

Check value of PatientSize before saving table in case it is a string instead of a number. Refs #896

Fixing mistake in previous - if PatientSize is not present then casting None to Decimal will raise TypeError. Refs #896
