Clade

* Added `-mbig-endian`, `-mlittle-endian` and `-mabi` options to CIF white list

* Fixed an issue with Clade that caused intercepted build process to fail

* Storage: Add ability to ignore decoding errors with `"Storage.decoding_errors": "ignore"` configuration option
* Storage: Use automatic encoding detection if user-specified encoding fails
* Storage: Fix passing encoding parameter between functions

* Add ability to manually add files to the Storage with "Storage.files_to_add" configuration option

* Add clade-trace script and associated Python API. This script allows to obtain possible call traces between functions in the callgraph, and visualize them with graphviz
* Add more options to the CC extension to parse
* Use full path to the required compiler when obtaining dependencies or preprocessing .c files in the CC extension
* Add --cif command line option to specify which version of CIF to use in the Info extension

Bug fix release:

* Do not try to delete CIF output directory if it does not exist
