Request: Reconstruct original file #15

be able to reconstruct the original file from sourcemap. something like the following:

smap, err := sourcemap.Parse(mapURL, b)
if err != nil {
	panic(err)
}

originalFile, err := smap.Reconstruct()

or, for the purpose of not loading a whole un-minified file into memory, we can pass in an int denoting number of lines you want reconstructed when you call Source(). Then, return a slice containing n strings which each represent a like. maybe something like this:

smap, err := sourcemap.Parse(mapURL, b)
if err != nil {
	panic(err)
}
line, column, peekCount := 5, 6789, 10
var originalLines []string
file, fn, line, col, originalLines, ok := smap.Source(line, column, peekCount)

originalLines would then have 5 lines above the mapped line, the mapped line, and 4 lines below, like so:

{
	"package main",
	"",
	"import \"fmt\"",
	"",
	"func main() {",
	"\tfor i := 0; i < 5; i++ {", // Mapped line
	"\t\tfmt.Println(\"howdy\")",
	"\t}",
	"}",
	"",
}
