feat: add getUintBE, findSequence, and encoding for uint8ArrayToString

[bjornstar]

There is some functionality from Buffer that was being used by file-type that seems to be generally useful, specifically getUintBE and the behavior of indexOf to take a buffer instead of a single byte's worth of an integer.

It would be great to get this in and released so it can be used in sindresorhus/file-type#633

I believe this one is ready to go and once we get a release we can move forward with:

• strtok3
• token-types
• file-type
• music-metadata

In that order.

You need to update the readme too.

In that order.

Explained in more detail here, I propose this steps:

1. token-types
2. strtok3
3. music-metadata: Ensure compatibility of strtok3 & token-types, ensure extensive unit tests are working
4. file-type
5. music-metadata: Replace Buffer dependency, release music-metadata

Since music-metadata has file-type as a dependency I put it before music-metadata. I suppose it's not required to be in that order, but it should work either way.

@bjornstar I noticed two issues in the indexOf implementation after merging. Can you review the fix? 79401bc

1. The inner loop resets index2 to 0 before breaking, which looks incorrect.
2. The outer loop's termination condition should use <= to include the last valid offset.

1. Sorry about that, the reset to 0 was leftover from a change that I did to satisfy a linting rule that I ended up not using.
2. Absolutely correct, good catch!
