Compatible version for R4.1.0 branch

[rbutleriii]

Hey, trying to get some test data for working with the Giotto R4.1.0 branch, but this fails with the R >= 4.3.0 requirement. I tried release versions back to v0.2.6.2. However even though that one installs, there aren't any mini datasets. I tried using getSpatialDataset, but that seems like it might be pointing to an empty location?

> getSpatialDataset("mini_seqFISH")
Error in data.table::fread(datasets_file, sep = "\t") :
  Input is empty or only contains BOM or terminal control characters
> getSpatialDataset("mini_seqFISH", directory=gDataDir())
Error in data.table::fread(datasets_file, sep = "\t") :
  Input is empty or only contains BOM or terminal control characters
> getSpatialDataset(dataset = "mini_seqFISH", directory=gDataDir())
Error in data.table::fread(datasets_file, sep = "\t") :
  Input is empty or only contains BOM or terminal control characters
> getSpatialDataset(dataset = "ST_OB1", directory=gDataDir())
Error in data.table::fread(datasets_file, sep = "\t") :
