Add option to disable sequence matching

## Short Description

Sequence matching is currently the most costly part for license matching. Some unscientific testing: scanning busybox 1.35.0 on my machine with sequence matching enabled takes a bit over 4 minutes, with sequence matching disabled it is 17 seconds.

I sometimes have a need to only do exact matches and don't care about the partial sequence matches. It would be nice to be able to disable this (and of course to have the option recorded in the JSON output so I know that sequence matching was disabled).

## **Describe the Update**

I would like to have a commandline option to disable sequence matching. This apparently is already exposed in the API (according to @pombredanne ) but it isn't an option in the CLI. Disabling sequence matching seriously speeds up scanning.

Of course, if the option is used it should be recorded in the JSON output.
