Use IPC conforming names for SOIC packages

[dbrgn]

Follow-up of #8, refs LibrePCB/librepcb-parts-generator#18.

Updated SOIC packages with IPC conforming names.

Old packages have been remapped where applicable:

One package has been deleted (EIAJ 48 pin), since the spec does not actually include 48 pin packages. I think we can safely assume that nobody started using that UUID already 😉

Version hasn't been updated, I don't think that's important at this stage.

(Last screenshot has a pin1 dot that's still too big, that has since been fixed.)

The IPC-7351B naming convention can be found here: https://ohm.bu.edu/~pbohn/__Engineering_Reference/pcb_layout/pcbmatrix/IPC-7x51%20&%20PCBM%20Land%20Pattern%20Naming%20Convention.pdf

What's the difference between SOIC127P762 and SOIC127P1524? Their footprints are exactly identical, but "nominal width" is different?

[dbrgn]

Oh, they shouldn't be identical. That's a bug, thanks for spotting!

[dbrgn]

Fixed in LibrePCB/librepcb-parts-generator@907a3cf.

Note: I removed 7.62mm wide parts with more than 32 leads and 15.24mm wide parts with less than 20 leads. They seem improbable to me.

[ubruhin]

Now you removed all packages in the base library^^ 😭

[dbrgn]

Whaat? 😂 😂 😂

Can't be, you must have been dreaming 🏃‍♂️

(I forgot to git-reset the pkg directory after deleting the old packages...)
