Optimize binary (#403)

* Optimize binary

Removes DWARF and symbol tables from the binary. From [https://pkg.go.dev/cmd/link](https://pkg.go.dev/cmd/link):
- `-s`: Omit the symbol table and debug information
- `-w`: Omit the DWARF symbol table.

Also trims the path in panics so they will start from project's local
folder. From [https://pkg.go.dev/cmd/go](https://pkg.go.dev/cmd/go):
- `trimpath`: remove all file system paths from the resulting executable. Instead of absolute file system paths, the recorded file names will begin either a module path@version (when using modules), or a plain import path (when using the standard library, or GOPATH).
