I think your diagnosis of the problem is correct (good catch), and I believe your code is fine, but I think there may be a simpler solution. Let me take a quick stab at it and see which way you like better. |

@marsupial correctly points out that we are unsafely passing a string_view.data() into both atoi and strchr, which is unsafe because there's no guarantee that a string_view is null-terminated. Ugh! He proposed a fix here: AcademySoftwareFoundation#800 and there's nothing wrong with it per se, but I suspected it could be done more simply, so this PR is my stab at it, using the `OIIO::Strutil::parse_*` functions.

Counter-proposal presented as #805. Thoughts? |

Description
Current code is passing string_view::data() to both strchr and atoi, which expect/require null terminated strings.
Tests
Part 1 of 2 which allows connecting individual components of aggregate types.
Second part includes proper test against ShadingSystemImpl::decode_connected_param.
