refactor: copy account module from @celo/cryptographic-utils@3.2.0

[jeanregisser]

Description

This is the first step to remove @celo/cryptographic-utils.

It copies the accounts module from it.

I've copied the exact same version used from the celo SDK: 3.2.0.
And listed the exact same NPM packages it was using internally.
This is to ensure it behaves the same.
We'll upgrade/remove these in a follow up PR.

I've slightly modified it to directly include some sub modules, which we didn't need to share.

• @celo/base/lib/account (some type definitions)
• @celo/base/lib/string (only 1 function used)

Test plan

• Tests pass

Related issues

• Part of RET-1185

Backwards compatibility

Yes

Network scalability

If a new NetworkId and/or Network are added in the future, the changes in this PR will:

• Continue to work without code changes, OR trigger a compilation error (guaranteeing we find it when a new network is added)

[jophish]

LGTM, assuming that the contents of account.ts and account.test.ts are basically copied verbatim (which, from a brief comparison to the originals, it looks like they are).

[jophish]

Is any part of this file meaningfully modified from the original? What of this ought to be reviewed, if any?

[jeanregisser]

Nothing was changed except some imports.
I did that in several steps: first step was 1:1 copy
Then small edits were made in d845d3b
