kdb+ Plugin Should Support Splayed Tables with Multiple sym Lists.

[FlyingOE]

Is your feature request related to a problem? Please describe.

The current plug-in assumes a universal sym list for all enumerated columns in a splayed table. This assumption will break on complicated schemas where each sym column in a splayed table may be enumerated by a different sym list.

Describe the solution you'd like

A new, enhanced API is needed to support multiple sym lists on a single splayed table.
