Fix Version/s: None
Use database expressions in DecimationProcessor and the related code. (Currently we are using Expression.java library to obtain column expression values when producing decimation (heatmap) data.
Since we are using database expressions for filtering, we need to make sure the same expressions are used to produce the data.
Ideally, we should be using db for all expression evaluation on the server side and remove all references to Expressions.java. We'll still keep Expression.js on client side for user-friendly column expression validation.
Currently server-side expression library is used in:
IpacTablePartProcessor.java (deprecated getDataFile - decimation)
HistogramProcessor.java (old single-trace charts)
XYGenericProcessor.java (old single-trace charts)

|Resolution||Done [ 10000 ]|
|Status||To Do [ 10001 ]||Invalid [ 11005 ]|
Server-side expression library was removed as a part of https://jira.lsstcorp.org/browse/DM-14125
Tatiana Goldina, did this work get done? If not, should we create a FIREFLY- ticket for it so we don't forget?
