Add --no-combine option to CLI

[yshalenyk]

spoonbill's cli currently does not have any option to disable combining behavior of the library. It may be good to have such, maybe through additional --no-combine option.
Also additional validation level would be required to --state-file option because analyzer do not track combined locations as child tables, so, changing list of combined types would require new analysis.

--no-combine sounds good.
