Mats Engstrom c1d49fe58b Add iteration over list of frequencies for best solution 
This patch adds support for icepll to try multiple input frequencies to
find the best crystal for the desired output frequency.

The values tested comes either from a specified file using-B, or from a
default set of frequencies from Mousers "normally stocked" crystal
oscillators.

The6P4C 578037dedf icepack: Fix Windows-only stack overflow in CRAM pbm generation (fixes #241) 
On Windows, attempting to generate a netpbm image of the CRAM with
`icepack -b` causes the tool to crash after writing only the netpbm
header due to a stack overflow. The bug did not appear on Linux.

This was traced to a large stack-allocated variable length array
(`tile_type`) inside `FpgaConfig::write_cram_pbm`. For an 8k ice40 with
4 banks, `cram_width = 872` and `cram_height = 272` the `tile_type`
array ends up at `4 * 872 * 272 * sizeof(uint32_t) =` 3794944 bytes, or
about 3.6 MiB.

The fix replaces the large stack VLA with an array of 4 (bank) 2D C++
vectors, moving the large amount of data to the heap. Even though the
fix is not in a Windows-specific code path (and hence applies to all
platforms), I think it's wise to eliminate such a large stack allocation
entirely.

The fix has been tested working on both Windows and an Ubuntu WSL
install.

Sylvain Munaut a7c42cd29b iceprog: Better reset of flash 
If the flash was in a 'weird' mode (like CRM, QPI, ...), sending
a continuous stream of 0xff should take it out of it.

It looks like the previous code was trying to do that, but
was only transferring 8 bits and then 2 bits which is way
too short.
