update README TRELLIS_INSTALL_PREFIX example 
`TRELLIS_INSTALL_PREFIX` will tell `next-pnr` to look in both `share` and `lib` directories.

See https://github.com/YosysHQ/nextpnr/pull/406#discussion_r387945570

4a9981ee77 pycontainers: Properly handle KeyErrors 
We raise a C++ exception to abort the rest of the execution of
the function.

At the same time we standardize on using a throw runtime error as the
method to avoid warning when not returning values. (some places
used this throw and some other used std::terminate)

Fixes #403

054be6fb67 build: Default the ECP5 and iCE40 roots to the install prefix 
If the user specifies a custom install prefix, chances are icestrom/trellis
are also in that prefix rather than the hardcoded /usr/local

Fixes #351

bb754441c8 gui: Fix undefined behavior in TreeModel. 
std::sort() requires the comparison function to return false for even
comparison. Returning true results in undefined behavior and a potential
segfault.
