feat: add build script (#13)

This commit adds pnpm scripts for compiling and running the
  typocomath package, and a convenience script `pnpm go` that does
  both in succession. It also configure pnpm to use a shell
  emulator so that it should work on Windows as well. Finally,
  it changes the directory for object files from obj to build.
  Resolves #9.

 A final (?) prototype for a refactor of mathjs, culminating the picomath, pocomath, typomath series. Provides an extensible core with "fuzzy" types for its operations, that can at any time generate exact .d.ts file for its current state.
 
-To build and run the prototype, run:
 
-```
-npx tsc
-echo '{"type": "module"}' > obj/package.json
-node obj
-```
+Convenience scripts:
+
+* `pnpm build` -- compile the package
+* `pnpm exec` -- run the compiled code produced by `pnpm build`
+* `pnpm go` -- both of the above in sequence.
