incorrect resolution detection at Panasonic MB1500

[rma945]

Describe the bug scanservjs can't parse --resolution parameter from scanimage output, becuase it don't contains expected regexp.

scanservsjs expects that all parameters from scanimage can be matched by this regexp but --resolution 75|100|150|200|300|400|600|1200dpi,... has a different format. Also, asResolution() function will do incorrect resolution options parse, becuase of non expected format of resolution parameters string. Because --resolution - is a mandatory parameter - scanservjs can't find scanner and resolution options can't be overrided by default config. I guess that as a workaround - we can add option for define a manual values for scanners if output from scanimage can't be parsed

scanimage output:
