DataArrayProxy converting dimensions from double to size_t from JSON

In `DataArrayProxy::readVector`, an array of numbers is read from JSON and converted to a `std::vector`. This function is used to read the tuple and component dimensions from JSON. This function does some checks on the range of acceptable values; however, it does not report any errors and has an implicit conversion between `double` and `size_t` inside its check. For exceedingly large datasets this would be an issue when attempting to read and write their dimensions.

A possible solution would be to store the dimensions as a string though this would affect backwards compatibility in pipeline files. Additionally better error reporting should be implemented to tell the user why the read failed.
