DEVREL-518 Feat: add send task to oft

[St0rmBr3w]

In this PR:

• adds a normalized send task like that in examples/oft-solana
• proof of work:
  • oft: https://testnet.layerzeroscan.com/tx/0xe06e49eadf715a6fcdab8dade2875ad7f2c80fbd666d71da33a1c203e6ab2ed7
  • maba: https://testnet.layerzeroscan.com/tx/0x1bcb9825c20a952b18234b8a7be9b0d0809ff598d57218d507661ebda520fc4e

Looks good.

Two improvement ideas for future:

1. Support OFT adapter
2. Support dynamic oapp-config parameter, because we accept such parameter in other commands

I have implemented 2 and tested:

approving, in future would be cool to see if it's possible to reuse the code between the examples
