LudvigOlsen/xpectr: xpectr 0.4.0

wrapStringAddin() now wraps short strings in paste0() as well. Previously, strings that were too short to be split were not wrapped.

Adds insertExpectationsCopyEnvAddin() addin. Same as insertExpectationsAddin() but where code is evaluated in a deep copy of the parent environment. This is especially useful when testing a function that alters non-local variables and has side effects (error/warnings/messages).

Multiple functions now allow working on a deep copy of the environment (see new copy_env argument). This is useful when testing a function that alters non-local variables. It is disabled by default to save memory.

gxs_function() now allows parallelization of the expectation generation process. Requires a backend, as setup with doParallel::registerDoParallel(4). Remember to set parallel = TRUE when calling gxs_function().

strip() and strip_msg() now strips ANSI control sequences by default.

strip() and strip_msg() can now make the strings lowercase (disabled by default).

capture_side_effects() disables crayon locally before evaluating the expression (by default). Avoids ANSI control sequences in messages.

capture_parse_eval_side_effects() now has the same options as capture_side_effects().

Bug fix: "Assigned data "NULL" must be compatible with existing data."
