Handle multiple chromosomes in one `query_granges`

Would be useful to automatically handle situations where query_granges spans multiple chromosomes. Could add an extra loop at the level of query or query_vcf/query_table.

Otherwise, stuff like this can happen:

 query_dat <- rbind(echodata::BST1[1:50,], 
                        echodata::LRRK2[1:50,], fill=TRUE)
     annot_dt <- echoannot::IMPACT_query(query_dat=query_dat,
                              populations="EUR")
     testthat::expect_equal(dim(annot_dt),c(13,1419))

Constructing GRanges query using min/max ranges across one or more chromosomes.
+ as_blocks=TRUE: Will query a single range per chromosome that covers all regions requested (plus anything in between).
