Update to latest version of ant-javacard

[conorpp]

I found that the 18.07.12 version of ant-javacard is having issues with importing external jar/exp files. The following configuration is unable to locate the .exp file.

        cap {
            ...
            dependencies {
                local {
                    jar 'build/javacard/tlv.jar'
                    exps 'build/javacard/'
                }
            }
        }

Similarly, if I make the equivalent tags in build.xml, ant-javacard-18.07.12 can't locate the exp. But if I update to 19.05.06 it all works great :)
