BREAKING CHANGES

• The --exclude-after-remap option is now functional and enabled by default. This causes the include, exclude and extension 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.
