read_data - using regex to determine if EDI or NEON source could be reconsidered

[mobb]

today, the read_data function parses the dataset identifier (regex) to decided to decide whether the source is pasta (EDI) or NEON. That seems a little risky, since a) the formats are very similar already (see screenshot - one character different), and b) adapting to a new ID format means hunting down the regex in code. We don't have plans to add another data source, but doing so would be difficult.

Consider using a switch (or function arg) to decide which read method to use.

@mobb We'll cross this bridge when we add support for another data source. The current implementation works fine for now. May I close this issue?
