• Resolves: issue #284 (sub-issue 1. -j1)

This commit is to enable a parallel build for debuild command by default.

According to debhelper manual: If your package can be built in parallel, please either use compat 10 or pass --parallel to dh. Then dpkg-buildpackage -j will work.

• https://manpages.debian.org/testing/debhelper/dh.1.en.html

How to evaluate:

• debuild

  export DEB_BUILD_OPTIONS='parallel=8' ; time debuild -us -uc  ;  export DEB_BUILD_OPTIONS=""

• pdebuild

  export DEB_BUILD_OPTIONS='parallel=8' ; time pdebuild  ;  export DEB_BUILD_OPTIONS=""

[Template] PR Description

In general, github system automatically copies your commit message for your convenience. Please remove unused part of the template after writing your own PR description with this template.

$ git commit -s filename1 filename2 ... [enter]

Summarize changes in around 50 characters or less

More detailed explanatory text, if necessary. Wrap it to about 72
characters or so. In some contexts, the first line is treated as the
subject of the commit and the rest of the text as the body. The
blank line separating the summary from the body is critical;
various tools like `log`, `shortlog` and `rebase` can get confused 
if you run the two together.

Further paragraphs come after blank lines.

**Changes proposed in this PR:**
- Bullet points are okay, too
- Typically a hyphen or asterisk is used for the bullet, preceded
  by a single space, with blank lines in between, but conventions vary here.

Resolves: #123

2. Run test: [ ]Passed [ ]Failed [* ]Skipped

**How to evaluate:**
