Stack trace wrong line number in REPL mode

[anhnhoktvn]

Hello, I found this bug:

With simple file like this:
File: test.ls

throw Error \line_1

Normally I get this error:

$ lsc test.ls 
Failed at: test.ls
Error: line_1
    at Object.<anonymous> (/home/anhnhoktvn/test.ls:1:7)

In REPL mode it would return wrong line number:

ls> require \./test
/home/anhnhoktvn/.nvm/versions/node/v13.11.0/pnpm-global/3/node_modules/.pnpm/registry.npmjs.org/livescript/1.6.0/node_modules/livescript/lib/node.js:57
      throw hackTrace(e, js, filename);
      ^

Error: line_1
    at Object.<anonymous> (/home/anhnhoktvn/test.ls:2:7)

2+ throw Error('line_1');

I expect it shows error at line 1 but in this case it shows line 2.
The source map seems not work in repl mode.
