The file name is the signature, such as DSDT,
and the contents are the binary table image.

Some tables, such as the SSDT, can have multiple instances.
If just one, the file is SSDT, but if 3 instances,
for example, it will be SSDT1, SSDT2, SSDT3

All static tables (besides teh RSDP and RSDT themselves
are exported.  Dynamic tables, such as SSDT op-regions that
are not declared in the RSDT, will be added in a subsequent patch.
