Update ANSI test cases 2 years ago

Support colon delimiter in ANSI escape sequences
# Both should work
    printf "\e[38;5;208mOption 1\e[m\nOption 2" | fzf --ansi
    printf "\e[38:5:208mOption 1\e[m\nOption 2" | fzf --ansi

This change makes ANSI parsing slightly slower.

This hides stdout output unless "go test -v" was run.

Speed up ANSI code processing (#2368)
This commit speeds up the parsing/processing of ANSI escape codes by
roughly 7.5x. The speedup is mostly accomplished by replacing the regex
with dedicated parsing logic (nextAnsiEscapeSequence()) and reducing the
number of allocations in extractColor().

Make fzf pass go vet
Add String() methods to types, so they can be printed with %s. Change
some %s format specifiers to %v, when the default string representation
is good enough. In Go 1.10, `go test` triggers a parallel `go vet`. So
this also makes fzf pass `go test`.

Update ANSI processor to handle more VT-100 escape sequences
The updated regular expression should include not all but most of the
frequently used ANSI sequences. Close #735.

Micro-optimizations
- Make structs smaller
- Introduce Result struct and use it to represent matched items instead of
  reusing Item struct for that purpose
- Avoid unnecessary memory allocation
- Avoid growing slice from the initial capacity
- Code cleanup
