build_ldats_analyses_plan: Build a drake plan for LDATS analysis
In weecology/MATSS-LDATS: LDA_TS meta-analysis using MATSS

Construct the expanded Drake plan for LDA time series analyses

1 2	build_ldats_analyses_plan(datasets, max_topics = c(3), nseeds = 4, nchangepoints = c(2, 3), formulas = c("time", "intercept"))

`datasets`	the drake plan for the datasets to analyze
`max_topics`	the maximum number of topics to try (the function will test a number of topics from 2 to `max_topics`)
`nseeds`	Number of seeds (replicate starts) to use for each value of `topics`. Must be conformable to `integer` value.
`nchangepoints`	Vector of integers: which numbers of changepoints to try.
`formulas`	Defaults to NULL. If nothing supplied, ~timename. If supplied, uses that.
