GRanges object with the cytobands of the specified genome.
The cytobands for some organisms and genome versions have been pre-downloaded from UCSC
and included in the
karyoploteR package. For any other genome,

cytoBandIdeo table from UCSC. If for
some reason it is not possible to retrieve the cytobands, it will return an empty
object. Setting the parameter
FALSE, the data included in the
package will be ignored and the cytobands will be downloaded from UCSC.
The genomes (and versions) with pre-downloaded cytobands are: hg19, hg38, mm9, mm10, rn5, rn6, danRer10, dm6, ce6 and sacCer3.
