8cc6a2fae5 Remove comment about the USRMCLK primitive being untested. 
Tested and verified working: the trivial configuration:

    module USRMCLK( USRMCLKI, USRMCLKTS );
        input USRMCLKI, USRMCLKTS;
    endmodule

    module top( input clk );
        reg[ 24:0 ] count = 0;

        always @( posedge clk ) begin
            count <= count + 1'b1;
        end

        USRMCLK mspi( .USRMCLKI( count[ 20 ] ), .USRMCLKTS( count[ 24 ] ) );
    endmodule

produces the expected output (toggling at high frequency, toggling
tri-state at lower frequency) on an LFE5U-85 when fed with an appropriate
clock.  See https://bayimg.com/AAnNKAAGO for an example.  The top
(magenta) trace is the MCLK line.

Wrong bits were being tested. [5:4] is what's controlling the output
enable path.

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

std::sort() requires the comparison function to return false for even
