feat: add boostLevel prop and support value segmentation

[offirgolan]

Hi @zpao, I've been using this lib for some time now and its been great! My most recent project has very specific requirements for the version and ECL which requires the following features to be added:

• Add boostLevel prop which gets passed into encodeSegments (Closes Missing “Boost ECC” flag causing discrepancy with other libraries #356)
  • Without this prop, even if we specify an ECL of L, it gets boosted to M
  • Let me know if you want me to change the name of this prop
• Add support for the value to be a string array that represents specific segments for improved version optimization. Since qrcodegen does single segment detection the version is increased in certain situations.
  • For example, https://foo.bar.com/ABC/DEF123 will become version 3, but if split like this ['https://foo.bar.com', '/ABC/DEF123'], it will become version 2 since the first segment is Bit and the second is alphanumeric.

@zpao bump 😄

I was hesitant when the issue was filed but this is pretty innocuous and backwards compatible. Let's do it.

I did want to make trunk v5 but that can wait since this would be a minor bump.
