Unused return value from write method in MulitTypeSymbolTable

[jeremiah-corrado]

In parseJson(), the return value from mem.writer().write(names) is stored but never used:

arkouda/src/MultiTypeSymbolTable.chpl

Lines 310 to 315 in 9721bec

	proc parseJson(names:string): [] string throws {
	var mem = openmem();
	var writer = mem.writer().write(names);
	var reader = mem.reader();
	var num_elements = 0;

In an upcoming Chapel PR (chapel-lang/chapel#20907), the fileWriter.write method will no longer return a boolean value, meaning that MulitTypeSymbolTable would fail to compile.

I'll open a PR to fix this issue.
