Feature/mros2 frag msg proto

[smoriemb]

This pull request is to have mROS2 on Mbed use the additional feature (fragmented data sending) added in the PR below.
[embeddedRTPS]
mROS-base/embeddedRTPS#11
[mROS2]
mROS-base/mros2#36

The modifications are below.

• Modifications for the custom messages to go along with the pull requests above
• Added two sample programs to demonstrate the new feature by publishing rather large messages.

Like mROS-base/mros2#36 above, this pull-request points to a submodule (mROS2) in my repository. I will update it to point to this repository after discussion.

But I think that we simply need to prepare long_text.txt for this requirement. And also, I think that modifying CMakeLists.txt will need to be maintained for future use.
Please simply prepare long_text.txt?

I had the same concern as you. I'd appreciate it if you could prepare some license-free documents to be stored. I passed the idea to store a novel from "Project Gutenberg" or something because I'm not sure if their license is OK to store there.
Is there any license-free document that belongs to you or your institute?

@smoriemb My idea is to locate the text file generated from README.md under Git control by executing commands in the following script manually once first.
