* Current `bin/prism lex` becomes `bin/prism lex_compat`
* Change `bin/prism lex` to only output prism tokens
I sometimes find myself wanting to look at tokens but on the cli
it only compares against other sources. Then I check the code and see that that `VERBOSE=1`
does something but the output isn't very readable
and doesn't fit on my terminal screen.
The new output looks like this:
```
$ bin/prism lex -e "foo(1, BAR, baz, 'bat')"
IDENTIFIER (1,0)-(1,3) "foo"
PARENTHESIS_LEFT (1,3)-(1,4) "("
INTEGER (1,4)-(1,5) "1"
COMMA (1,5)-(1,6) ","
CONSTANT (1,7)-(1,10) "BAR"
COMMA (1,10)-(1,11) ","
IDENTIFIER (1,12)-(1,15) "baz"
COMMA (1,15)-(1,16) ","
STRING_BEGIN (1,17)-(1,18) "'"
STRING_CONTENT (1,18)-(1,21) "bat"
STRING_END (1,21)-(1,22) "'"
PARENTHESIS_RIGHT (1,22)-(1,23) ")"
EOF (1,23)-(1,23) ""
```
