expo: Allow setting the start of the dynamic-ID range
Provide a way to set this value so that it is easy to separate the
statically allocated IDs (generated by the caller) from those
generated dynamically by expo itself.

+ * Dynamic IDs (for objects not in the enum) are intended to be used for

+ * above the static IDs.
+ *
+ * Use this function to set the start of the dynamic range, making sure that the
+ * value is higher than all the statically allocated IDs.
