adding ability to use a cache with accessors

[ptahmose]

Description

• adding the option to use a cache with the accessors
• an implementation of a simple cache
• adding an example of its usage to CZIcmd
• unrelated: updated CLI11 to latest version (c.f. here), no changes in functionality expected for our usage
• added an option to enable/disable the"non-visible-tile-optimization" from non-visible-tiles-optimization for multi-tile-composition #78 to CZICmd.

The PR is addressing #77.

With the CZI-document mentioned in #73 I get the following runtimes for
