BREAKING CHANGES

• The --exclude-after-remap option is now functional and enabled by default. This causes the include and exclude lists to be processed after using source maps to determine the original filename of sources.
• Add a file named 'index.json' to the .nyc_output/processinfo directory, which has a different format from the other files in this dir.
• Change the data type of the pid/ppid fields in processinfo files
• nyc instrument now honors include and exclude settings, potentially resulting in some files that were previously instrumented being ignored.
• The plugins option has been renamed to parser-plugins.
• The logic involving include/exclude processing has changed. Results should be verified to ensure all desired sources have coverage data.
• nyc instrument now enables the --es-module option by default. This can cause failures to instrument scripts which violate 'use strict' rules.
