Function tryParseTimeSignature

tryParseTimeSignature(text: string): ParseResult<TimeSignature>
Parse a time signature, reporting failure instead of throwing it.

The same reading as parseTimeSignature — that function is this one with its error thrown — for the callers where text that does not parse yet is the normal state of the input rather than a fault.
Parameters
- text: string
  The signature text.
Returns ParseResult<TimeSignature>
The signature, or the error explaining why the text is not one.
Example
```
import { tryParseTimeSignature } from '@libraz/libcantus';
const result = tryParseTimeSignature('7/8');
result.ok ? result.value.numerator : result.error.message;
```
