Move chromosome:start-end parsing into it's own function in hgFind so we can call just that code from elsewhere. Add a defaultPosition check for assembly hub into hubCheck that verifies the requested chromosome exists for that assembly. Do not warn if the range is too large since we actually silently accept that anyways and clamp to the chromosome ends. refs #37126
