Inconsistencies in /cub_icml. Updating CUB class name.

[jingliao132]

Recently, I downloaded the latest CUB datasets and found some inconsistencies between the caption classes and CUB image classes. These classes have been renamed as:
009.Brewers_Blackbird -> 009.Brewer_Blackbird
022.Chuck_wills_Widow -> 022.Chuck_will_Widow
023.Brandts_Cormorant -> 023.Brandt_Cormorant
061.Heermanns_Gull -> 061.Heermann_Gull
067.Annas_Hummingbird -> 067.Anna_Hummingbird
093.Clarks_Nutcracker -> 093.Clark_Nutcracker
098.Scotts_Oriole -> 098.Scott_Oriole
113.Bairds_Sparrow -> 113.Baird_Sparrow
115.Brewers_Sparrow -> 115.Brewer_Sparrow
122.Harriss_Sparrow -> 122.Harris_Sparrow
123.Henslows_Sparrow -> 123.Henslow_Sparrow
124.Le_Contes_Sparrow -> 124.Le_Conte_Sparrow
125.Lincolns_Sparrow -> 125.Lincoln_Sparrow
126.Nelson_Sparrow -> 126.Nelson_Sharp_tailed_Sparrow
178.Swainsons_Warbler -> 178.Swainson_Warbler
180.Wilsons_Warbler -> 180.Wilson_Warbler
193.Bewicks_Wren -> 193.Bewick_Wren

Please rename these folders in cub/icml.
