chore(deps) update penlight from 1.5.4 to 1.7.0

#### 1.7.0 (2019-10-14)

##### New features

- utils.quote_arg will now optionally take an array of arguments and escape them all into a single string.
- app.parse_args now accepts a 3rd parameter with a list of valid flags and aliases
- app.script_name returns the name of the current script (previously a private function)

##### Changes

- Documentation updates
- utils.quit: exit message is no longer required, and closes the Lua state (on 5.2+).
- utils.assert_arg and utils.assert_string: now return the validated value
- pl.compat: now exports the jit and jit52 flags
- pretty.write: now sorts the output for easier diffs #293

##### Fixes

- utils.raise changed the global on_error-level when passing in bad arguments
- utils.writefile now checks and returns errors when writing
- compat.execute now handles the Windows exitcode -1 properly
- types.is_empty would return true on spaces always, indepedent of the parameter
- types.to_bool will now compare case-insensitive for the extra passed strings
- app.require_here will now properly handle an absolute base path
- stringx.split will no longer append an empty match if the number of requested elements has already been reached #295
- path.common_prefix and path.relpath return the result in the original casing (only impacted Windows) #297
- dir.copyfile, dir.movefile, and dir.makepath create the new file/path with the requested casing, and no longer force lowercase (only impacted Windows) #297
- added a missing assertion on path.getmtime #291
- stringx.rpartition returned bad results on a not-found #299

#### 1.6.0 (2018-11-23)

##### New features

- pl.compat now provides unpack as table.unpack on Lua 5.1

##### Changes

- utils.unpack is now documented and respects .n field of its argument.
- tablex.deepcopy and tablex.deepcompare are now cycle aware (#262)
- Installing through LuaRocks will now include the full rendered documentation

##### Fixes

- Fixed seq.last returning nil instead of an empty list when given an empty iterator (#253).
- pl.template now applies tostring when substituting values in templates, avoiding errors when they are not strings or numbers (#256).
- Fixed pl.import_into not importing some Penlight modules (#268).
- Fixed version number stuck at 1.5.2 (#260).
- Fixed types.is_empty returning true on tables containing false key (#267).
- Fixed test.assertraise throwing an error when passed an array with a function to call plus its arguments (#272).
- Fixed test.assertraise not throwing an error when given function does not error but instead returns a string matching given error pattern.
- Fixed placeholder expressions being evaluated with wrong precedence of binary and unary negation.
- Fixed placeholder expressions being evaluated assuming wrong binary operator associativity (e.g. _1-(_2+_3) was evaluated as (_1-_2)+_3.
- Fixed placeholder expressions being evaluated as if unary operators take precedence over power operator (e.g. (-_1)^_2) was evaluated as -(_1^2)).
- Fixed vulnerable backtracking pattern in pl.stringx.strip (#275)
