added Reader::Config::instrumentMetadataError to encapsulate the "if(unknownInstrumentIsError) throw; else print warning" logic
made failures reading WIFF metadata optionally fatal (depending on ignoreUnknownInstrumentError setting)
fixed ignoreUnknownInstrumentError default value to be false
fixed reading CE from WIFF file spectra
added fallback handling for when calling centroiding or framing zeros on WIFF2 spectra throws exceptions but the profile/unframed spectra are available
