Describe the issue
The parser fails and stops parsing if a comment is at the end of a line defining an element with a variable number of possible elements following the token. For example, when defining a line like l 1 3 # First line, it's unknown how many vertex indices follow after the l. The while loop condition only looks for new line characters. Subsequently, the parser fails when it encounters the # character.

To Reproduce
Steps to reproduce the behaviour:

1. Compile TinyObjLoader
2. Load the .obj-file in the attached .zip-archive via ParseFromFile: linien.zip
3. See error: Failed to parse `l' line (e.g. a zero value for vertex index. Line 43).

For convenience, try this example project:
tiny_obj_loader_parser_bug.zip

Remarks
This bug only applies to tokens that have a variable number of elements:

• vw (skin weight)
• l (line)
• p (points)
• f (face)
• g (group)

Expected behaviour
The parser should stop parsing a line once it reaches the comment character #.
