Line 3: The name of the file that this source map is associated with.
Line 4: The number of lines represented in the sourcemap.
Line 5: "lineMaps" field is a JSON array, where each entry represents a
line in the generated text.
Line 6: A line entry, representing a series of line segments, where each
segment encodes an mappings-id and repetition count.
Line 9: An optional source root, useful for relocating source files on a
server or removing repeated prefix values in the "sources" entry.
Line 10: A list of sources used by the "mappings" entry relative to the
sourceRoot.
Line 11: A list of symbol names used by the "mapping" entry. This list
may be incomplete.
Line 12: The mappings field.
Line 13: Each entry represent a block of text in the original source, and

The source file name
The line in the source file the text begins
The column in the line that the text begins
An optional name (from the original source) that this entry represents.
This can either be an string or index into the "names" field.
