Changes needed for --cid-base option in go-ipfs (simplified vesion)

[kevina]

Simplified version of #8

Do not merge until ipfs/kubo#5789 is approved.

@Stebalien when gx publishing this should it I use minor or patch I would think minor since it adds a new package.

[magik6k]

Code LGTM, but it would be really nice to get some tests, especially for --filter in cid-fmt

[Stebalien]

Same as @magik6k. LGTM but needs tests.

[kevina]

Okay I added tests and this should be good to go. Will merge once I get an approving review.

[magik6k]

Can you enable CI here? Should be as simple as mkdir ci; echo 'golang()' > ci/Jenkinsfile + giving ci team on github write access (to set commit status)

[kevina]

Someone with the write permissions will need to activate Jenkins and Travis...

[Stebalien]

I've activated travis. Not sure how to activate Jenkins.

[Stebalien]

(I assume this was OK to merge... If not, we can revert it)

No, not really, the commits to activate the CI's where untested and I was waiting for them to be activated before I merged this PR. If that did not happen I would of removed the commit from the P.R. to do it separately. In fact the Travis CI need some fixing.

Reverting will just make this messier I will create another P.R.

Just give ci team on GitHub write access to this repo

[Stebalien]

@magik6k done.

@kevina got it. Merged your fix as everything seems to work now.

@Stebalien This needs to be gx-published. Should we bump the minor version or just the patch level? I would think minor since it adds a new package.

In the interest of pushing ipfs/kubo#5789 forward, I want ahead and gx published this as a minor release.

[Stebalien]

Either way, just don't bump to version 1.0.

For packages <= 1.0, I usually only bump the minor for breaking changes but that's mostly a habit from working with rust/js packages (https://nodesource.com/blog/semver-tilde-and-caret/#caretmajorzero).
