Add dev command: extension dumper for SPC

[crazywhalecc]

What is extension dumper

Print required extensions from your composer project.

1. Read custom vendor/composer/installed.json or vendor/composer/installed.php file.
2. Get all extensions from composer generated file (reading ext-* word).
3. Print extensions.

As we already do this with bash and jq for composer.json maybe i can start implementing this if its more clear what the goal of this should be:

cat composer.json | jq -r '[.require | keys[] | select(startswith("ext-")) | split("ext-") | join("")] | join(" ")'
curl iconv imap json mbstring pcntl pcre pdo redis

or based on installed.json:

cat vendor/composer/installed.json | jq -r '[.packages[] | select(.require) | .require | keys[] | select(startswith("ext-")) | split("ext-") | join("")] | unique | join(" ")'
ctype curl dom filter iconv intl json libxml mbstring phar posix redis simplexml tokenizer xml xmlwriter

composer.lock in the same project! returns another set of extensions:

cat composer.lock | jq -r '[.packages[] | select(.require) | .require | keys[] | select(startswith("ext-")) | split("ext-") | join("")] | unique | join(" ")'
ctype curl dom filter iconv intl json mbstring posix redis tokenizer
