Added new readme's to change static script location

Cantordust seems to not function properly when not located in ~/ghidra_scripts. This fix will tell the user that scripts should be moved to ~/ghidra_scripts. The error associated is:
`> Unable to load script: Cantordust.java

detail: The class could not be found. It must be the public class of the .java file: cantordust.Cantordust not found by 3ef1c2b6 [55]. A long term solution to make this path agnostic is suggested however everything is functional when pulled into the ~/ghidra_scripts` directory.

PR 8 would also probably solve this .... if it ever gets merged.
