(enh) wren_modules are searched until a matching library is found
- this means you can now use both $HOME/wren_modules (global modules)
- as well a local ./wren_modules for individual projects
- the "closest" match wins, allowing local to win out over global
- this is technically a breaking change from wren-cli which stops at the first wren_modules it finds
(fix) absolute script paths work on Windows now
(fix) mode test
(fix) cwd test on windows
(fix) pid test on Windows
(fix) memory allocation/slot allocation issues
(fix) freeing stdinStream memory too early
(enh) Add CI and build artifacts with Linux, Windows, and Mac

(chore) Auto-build and test binary releases for Windows, Mac, Linux platforms on tagged versions
(enh) Integrate Mirror functionality for stack trace introspection (via wren-essentials)
(fix) Stdin.readByte now propery removes single bytes from buffer
(enh) support scripts at absolute paths
(enh) controlled crashes should not include CLI script in stack trace
(enh) Add Runtime API for getting information about the runtime
(enh) Add Process.exit() and Process.exit(code)
(enh) Add Stderr.write(_) and Stderr.print(_)
(fix) Process.exit() should actually work properly now
(enh) Add Process.exec(command, [arguments, [workingDirectory, [environment]]])

includes Wren Core 0.4
rewrite a good portion of CLI codebase in pure Wren code (as much as possible)
module resolution and loading is now brokered by Wren code
flush stdout before quitting wren-lang#77
add -e flag for code evaluation wren-lang#11
add -h and -v flags wren-lang#88
add - flag for read script from stdin wren-lang#55 (comment)
add experimental native binary module/library loading support wren-lang#52
- see https://github.com/joshgoebel/wren-essentials for how to build a sample binary library
- import "wren_essentials:essentials" loads the library from wren_modules/libwren_essentials.dylib and then imports the essentials module from that library
based on wren-cli codebase (9c6b6933722)
