Title: Add :load command to REPL that can compile and load external libraries 

The :load command takes a list of crate names (with or without file extension), compiles them into shared libraries if necessary, and loads them to make them available in the current session. It can also load crates from directories outside the current one.

Example:
```
rusti> :load crate1.rc src/crate2
compiling crate1...
compiling src/crate2...
crates loaded: crate1 src/crate2
rusti>
```
