Library assumes all flash starts at 0x08000000 #19

In my use case, I am hacking a product with a SoC that has some audio codec ROM code that's too cumbersome to reimplement for PC, so I'm using QEMU to emulate the code. I'm using the LM3S6965 EVB machine for emulation, and it has flash starting at 0x00000000. I was a bit confused why the library would raise an error when just initializing it, and it turned out to be trying to get the fault handler at 0x0800000c, which doesn't exist on this emulated SoC. The flash base address should taken in as an optional argument when initializing.

hey, yeah, the nvic gets mapped anyway to 0x0, so i think this fix should be the correct one. no need to parametrize the nvic mapping thus...
