adding h_nelec_sed and h_e_sed to SRTrueCaloPoint for better recombination studies

Quick checklist

• [ V ] Have you run git fetch and pulled the latest changes from the branch you're basing your PR against?
• If you're adding new classes, have you added them to classes_def.xml in the relevant directory?
• [ V ] Have you added a checksum in classes_def.xml to any and all new classes you're implementing, and rebuilt?
• [ V ] If you're updating classes, have you incremented the ClassVersion by one compared to develop in classes_def.xml?

Description

Adding h_nelec_sed and h_e_sed to SRTrueCaloPoint for better recombination studies.
These variables will save deposited energy and number of ionizing electrons collected from simEnergyDeposit within wire channel position +- spacing/2. They correspond to the true deposited energy and number of ionizing electrons in the hit pitch.

Looks worth doing, thanks Sungbin!

One tiny comment about typos :)

I'll wait until the PR is not-draft to approve, I assume there are complementary PRs coming in other repositories?

Couple of typos in the comments: spacig-->spacing and boarder-->border

Hi @henrylay97 , thank you for the review. I've fixed the typos!

I have a working version of sbncode (link) for the new variables but it works only for SBND.
I use wire position only in Z-coordinate for selecting SED corresponding to a wire channel.
It works for SBND's collection plane but not for any of ICARUS's plane.
This is main reason why I have changed this PR to draft.
I hope to get some time to develop on generality of the custom sbncode development.
