First release.
Ships GLPK's stand-alone glpsol solver, so solving MathProg (GMPL),
CPLEX LP and MPS models needs no separate GLPK installation on Windows and
macOS.
glpsol_path() returns the bundled executable; glpsol_run() runs it in a
separate process with an optional live log and a timeout that also covers
model translation and writing the solution, which GLPK's own --tmlim does
not. glpk_version() reports the version of the linked library.
glpsol_read_solution() reads the solution file written with -w (basic,
interior-point or integer) into data frames, with row and column names
attached from the problem file written with --wglp.
